Shortly after retiring at the end of the previous series, Harry Bosch now works as a private investigator. He is asked to investigate a personal matter by billionaire Whitney Vance, namely, to find the woman he impregnated while in college to see if he has an heir. Meanwhile, his daughter Maddie is in training to become a police officer, but struggles with harsh training officers. Honey Chandler, recovered from her injuries, attends the trial of Carl Rogers, who attempted to have her killed, along with Bosch and Maddie. A mistrial is declared, and the district attorney decides not to try again, angering all three. Chandler goes back to work and is given the case of Jeffery Herstadt, a homeless man with mental problems accused of killing a respected doctor, who has confessed. She asks Bosch to look at the confession and testify about possible coercion, and Maddie convinces him to do so. After discovering the confession was indeed coerced, he does, but Chandler is shortly afterward shown DNA evidence found on the victim seemingly proving Herstadt's guilt anyway. Investigating for Vance, Bosch finds the woman is now dead, but intends to continue searching for the child. Vance agrees, but is later found unresponsive by his secretary. Chandler asks Bosch to help her get Rogers convicted, which he agrees to, but says they will do it "his way". Meanwhile, an earthquake damages Bosch's house, causing a city inspector to label it unsafe.

After Whitney Vance is revealed to be fine, his intended successor, Philip Corwin, worries about why he hired a private investigator, and expresses this to John Creighton, the head of Vance's security company. Chandler, despite struggling with the trauma of being shot, finds out how Herstadt's DNA ended up on the murder victim, and reveals it in court, causing the DA to drop the case. Afterward, Detective Gustafson, the detective in charge of the case, accosts her, and claims Bosch has undone everything he did with the badge. In his investigation into Carl Rogers, Bosch has Chandler convince Judge Sobel's daughter to file a wrongful death suit against Rogers. He also has his tech expert, Maurice "Mo" Bassi, plant bugs on Rogers' vehicles. Watching a deposition, he finds that Rogers may be affiliated with Russian mobsters, and discovers he is being tracked. He later overhears Rogers receiving a call from his financier, Simon Wakefield, that the Russians want to meet, which unnerves Rogers. Later, two Russians, Alex and Lev, kill a man who stole from their boss. In his investigation into Vance's child, he finds the home where the woman died, and discovers she gave birth to a boy who was adopted under the name Dominick Santanello. Meanwhile, Maddie screws up an arrest, but her training officer, Reyna Vasquez, covers it up when she manages to find where the suspect went, telling her she will take a chance on her.

Bosch and Chandler visit Willy Datz, the mobster through whom Rogers hired the hitman, in prison, where Chandler intimidates him into revealing he changed his story after the Russians threatened his family, to the disapproval of her boss. Maddie and Vasquez are called to the scene of a rape, where Maddie identifies the rapist's point of entry as a window with a cut screen. Later, she offers to speak to the victim if she ever needs help, to Vasquez' disapproval. Bosch investigates Dominick Santanello, and discovers he died in Vietnam in 1972. He informs Vance, and Vance asks him to find out anything else about Dominick. He is followed from the meeting by another car, but loses it, before Mo informs him that Rogers is headed to a meeting with the Russians, and heads to the meeting. At the meeting, Alex and Lev threaten Rogers and Wakefield to pay them 30 million dollars, which Rogers agrees to, but claims he will need time. They give him a week. Bosch eavesdrops, but is discovered and chased away, eventually escaping. After going to an old contact who identifies the Russians as brothers Alexei and Lev Ivanovich, high ranking Bratva members, he informs Chandler, and tells her the calls Rogers made while incarcerated were to a gas station in Bakersfield. Afterward, he arranges to meet Dominick's sister, Olivia MacDonald. On his way to the meeting he is followed by the car, but loses it and goes to the meeting in a rental. As he leaves, he is shown to be observed through a drone by Vance's security company.

Bosch meets Olivia, and when shown Dominick's belongings, he finds a roll of film of a woman and a baby she does not recognize. He has it enhanced, and finds it was taken when Dominick would have been in Vietnam, and considers he may have gone AWOL to see the girl, who may have been his daughter. Olivia is later visited by two men from Vance's security company, posing as representatives of the Veteran's Association, and informs Bosch that they asked her if Dominick had any children. Bosch realizes he is still being tracked, and Mo informs him he is probably watched by a drone. When trying to report to Vance, he meets David Sloan, Vance's valet and butler, who tells him Vance is ill, and to report to him. He refuses, and asks Chandler to provide him with a lab to confirm Dominick's heritage. Chandler receives the case of Russell Barnes, who wants to sue the LAPD for wrongful arrest after being incorrectly identified by facial recognition software. She proves to the detective that Barnes is innocent. When the department offers a settlement of 1.2 million, Chandler wishes to press further, but Barnes decides to take the money. Meanwhile, Bosch and Chandler publicly serve Rogers a subpoena for wrongful death, and when the Russians find out, Lev threatens Rogers. When Rogers meets Wakefield and two other men at a diner, Bosch has his former coworkers Crate and Barrel listen to their conversation and follow them. They find the other men are Russ Pensak, who owns a supposedly abandoned oil refinery, and Leo Aslan, who owns a shipping company, and notice several tanker trucks entering and leaving the refinery. Bosch also listens to a recording of the conversation, where Rogers mentions having 48 hours. Bosch infiltrates the refinery and finds that they are stealing gas, and have set IEDs on the pipe. After sending proof to Chandler, he attempts to leave, but is caught by a security guard and held at gunpoint. Meanwhile, Maddie continues to struggle with the rape case, and Vance's secretary, Ida, is shown to know how to forge his signature.

Bosch bluffs his way out of the building by pretending to be a security officer doing a surprise inspection, and informs Chandler that Rogers intends to siphon more gas by installing a second tap when the pipe is shut down for maintenance. Using this information, Chandler attempts to intimidate Wakefield, but this exchange is seen by Alexei. He eventually decides to give up information, but is killed by Lev before he can. Chandler finds him dead and takes his phone, delivering it to Mo, who recovers the information on it, revealing that the new tap will be installed that night, as well as a blueprint called Plano. Realizing from the full conversation that the detonator for the IEDs is on Aslan's key fob, Mo and Bosch make a plan to detonate the pipe before they steal the gas by hijacking the detonator's signal, while Chandler contacts Rogers' lawyer Glenn Kading to negotiate a deal for the civil suit with Rogers personally. That night, Bosch is forced to approach Aslan face to face to hijack the signal, but they blow up the pipe before any gas is stolen. In a meeting with Chandler and Kading, Rogers receives a message that the pipe was destroyed, and Chandler offers him the deal to turn himself in for everything he did in exchange for protection from the Russians. Meanwhile, as Bosch continues to investigate Dominick, Vance is shown to be comatose, while Sloan interferes with Bosch's communications. Bosch tracks down a friend of Dominick to see if he knew if Dominick had children, and shows him the photo. The friend recognizes the woman, telling Bosch that she was a photojournalist, and that Dominick was in love with her. Later, after Bosch hears a news report that Vance is dead, he is contacted by Sloan, who tells him his services are no longer necessary. Hearing the same report, Corwin tells Creighton to stop observing Bosch. Meanwhile, Maddie helps the rape victim install a new security system. Afterwards, she has a talk with Harry, who tells her she needs to decide if being a cop is a mission or just a job. Inspired by this, she reviews an app the victim told her about on what is happening in the neighborhood, finding more reports of break ins through cut screens.

After calling Chandler and unsuccessfully asking for leniency, Kading delivers a vial of drugs to Rogers at the safe house he has been sequestered at. The next morning he uses them to incapacitate his guards and escape. Alexei and Lev, after interrogating Rogers' girlfriend for his whereabouts, meet up with their father Maxim, and find and kill Kading. After finding a newspaper article denouncing him and Chandler for defending Herstadt, Bosch decides to find the real killer, while Chandler discovers that Plano is one of two modified shipping containers arriving at South Beach. After finding Rogers has escaped, Chandler and Bosch investigate the two containers under the assumption that Rogers will use one of them to escape overseas. Chandler witnesses the Russians store Kading's body in one of the containers, then kill Rogers and seal both bodies in the container before leaving. Meanwhile, Bosch receives Vance's will, which names him executor and Ida as receiving 10 million dollars, and Chandler tells him not to tell anyone until he can confirm whether Vance had an heir. Paulina Calderon, a friend of Maddie, is shot during a traffic stop, and Maddie is told to help inform the family. When Bosch hears of the shooting and confirms Maddie was not the victim, he realizes who is following him, and confronts Creighton, who attempts to intimidate him into dropping his investigation. He meets Maddie, and after she tells him she still wants to be a cop, he tells her about a time he was shot and Eleanor, Maddie's mother and a former FBI agent, saved him. Afterward, he gives Vance's will to Jerry Edgar, his former partner, for safekeeping.

Chandler reveals she has no peace from Rogers being gone, while Willy Datz is shanked in prison and her boss and the FBI question her about it. When the FBI give details they couldn't know without having illegally recorded their conversation with Datz, she warns Bosch, who finds a bug in his office, and later hears rumors that the Bratva had Datz killed for talking to her, which are seemingly confirmed when an inmate with a Russian name is found to be the killer. Bosch investigates the murder of the doctor and is threatened by Gustafson. He is warned that Gustafson is a glory hound, and later discovers he didn't properly investigate the murder. When speaking to the family of the doctor, he finds that the doctor had a meeting with a medical board investigator which his family did not know about. In Vance's case, in the wake of Vance's death, Corwin fires Ida. Bosch is visited by the police, who question him about why Vance hired him. He lies, and tells them to investigate Sloan. When the friend of Dominick tells him the name of the paper the woman worked for, he investigates and finds the name of the woman, Gabriela Lida. When he tracks her down, she reveals the daughter she had with Dominick is an artist named Vibiana Veracruz, who has a son of her own, Gilberto, and they make plans for Bosch to meet her. As they depart, they are shown to be observed by Sloan. Meanwhile, Maddie hears about a break in committed by the same suspect in the rape case. She meets the rape victim again, but upsets her when she is unable to provide further information. While still in search of the suspect who shot Paulina, his girlfriend who wants out calls her mother for money, who tells the police, and a drop is set up. When they go to pick up the money, the police, including Maddie, attempt to arrest them, but the arrest goes horribly wrong as they are both shot dead.

Bosch meets Vibiana, who agrees to do a DNA test to prove her heritage. She later finds that she is being observed by Sloan, and tells Bosch. When Bosch confronts Sloan, he informs him that he wants to help as per Vance's wishes, which Bosch accepts and lets him move Vibiana and her son to a safe house. Meanwhile, in the doctor's case, he speaks to the medical representative and finds the doctor discovered one of his employees was writing fake prescriptions for nonexistent patients and was killed before he had a chance to follow up, which the representative informed Gustafson about. Later, Bosch finds the wounds were precise enough for the killer to have had a background in medicine. Maddie is questioned about the shooting in a way that suggests the investigator believes the officers involved are guilty of misconduct, and is later informed by Bosch that SIS has a record of corruption. She helps a fellow officer, Rico Perez help out Paulina, and later hooks up with him. The next day, she and Vasquez arrest a man apparently breaking into a house, but he turns out not to be the rapist from her earlier case. Meanwhile, Chandler files a wrongful death suit against SIS for the death of the suspect's girlfriend. Speaking to her family, she gets the name of the SIS lieutenant, Spencer Cosgrove, and has Mo investigate him, finding that his ex-wife has a restraining order against him. She also attempts to contact Detective Morrison, the detective in the case, only to be rebuffed. Cosgrove later asks Morrison to support him, which he seemingly agrees to, but is later shown listening to a conversation he had with the victim's mother, possibly having second thoughts. Bosch discusses Vance's case with Chandler, and their conversation is overheard by Corwin and Creighton. Corwin worries about inheriting the company, suggests having Vibiana killed, and attempts to intimidate Creighton into helping him. Creighton later meets a foreign assassin, and tells her he has a job for her.

The woman Creighton hired investigates Bosch's office, and Bosch disables the bug in response. She later observes Chandler entering a genetic testing lab, which later mysteriously catches fire, though Chandler still confirms that Vibiana's DNA is a match for Vance. In the doctor's case, Bosch finds the name of the doctor writing fake prescriptions, but the homeless he prescribed them for do not have the pills. In Vance's case, Bosch visits Ida, tells her what was in the envelope, and asks her to sign an affidavit to establish authenticity. The police show up to investigate Bosch again in Vance's case. Knowing of Sloan's innocence now, he tells them about Vance's son, in exchange for them telling him Vance was murdered, and that Ida had access to his office and wrote his letters for him. When they show him pictures of the office that show the pen went missing after the murder, he realizes who killed Vance. He and Chandler have Ida sign the affidavit, and afterwards, reveal they know she killed Vance, and that she wrote the will. When they threaten to turn her in, she admits Vance asked her to write the will when he believed he was dying, and she put herself in it without his knowledge, but after he recovered and wanted to change it she killed him to prevent him from finding out, after which she is arrested. Meanwhile, investigating the rapist, Maddie and Vasquez discover a luchador mask that could belong to him, and Maddie calls a city inspector about what he may have seen, who is shown secretly looking at pictures of Maddie. Detective Morrison later admits to the police that he believes the suspect's girlfriend was innocent. Meanwhile, the hired assassin observes Sloan meeting Bosch, and informs Creighton that she will take care of it. That night, Vibiana calls Bosch and tells him Sloan seems suspicious. Bosch realizes she has been found and races to her building as the assassin enters it.

Bosch tricks the assassin and rescues Vibiana and her son, and has Mo recover camera footage showing the killer's face and gun. In the doctor's case, Bosch gives the evidence he has collected to Gustafson, including a video recorded by Mo of the doctor selling pills, ensuring the doctor's arrest, and afterwards, is sent a video of the woman killing Sloan. Bosch kidnaps Creighton, and uses tactics from Afghanistan to force him to reveal how to contact his assassin. Using Creighton and Mo, he sets a trap for the woman, and eventually manages to kill her. He then releases Creighton, but warns him he will be arrested if there are any further attempts on Vibiana's life. Afterwards, Chandler publicly reveals Vance had heirs, ensuring Bosch's threat. In the wrongful death suit, Chandler gets the body camera footage of the shooting, but Bosch tells her to leave Maddie out of it. She later shows Morrison that Cosgrove planted the gun and asks him to do the right thing. He gives her more information, on the condition that she does not settle. Meanwhile, Maddie sees and speaks to the city inspector who put up the notice, Kurt Dockweiler, which seems to unnerve him. Later, she and Vasquez find an injured man who dies, upsetting her. She is later visited by Chandler, who tells her the civil suit may destroy careers, and after she expresses disapproval, asks if she wants to see justice served. Maddie later meets Bosch, telling him how afraid she was when he didn't respond to her calls, and they reaffirm their bond. When she goes home, it appears someone else is in her apartment. At an exhibition by Vibiana that night, Chandler tells Bosch that Maddie may have to testify, as her camera saw Cosgrove plant the gun. Disgusted, Bosch leaves to meet Maddie. Arriving at her apartment, he finds it seemingly empty, with one window having a cut screen.

In a flashback, Maddie is attacked in her apartment by the Screen Cutter, revealed to be Kurt Dockweiler, who takes her to his truck and escapes with her. In the present, Edgar and Joan Bennett, working the case, allow Bosch to sit in while they brief their captain, and he hears that they believe the Screen Cutter to be her abductor. He is sent home after an outburst following the reveal that they have no leads. Bosch calls Mo on his way home and asks him to track any digital data of Maddie in the days before her abduction, nearly having a car accident while doing so. Finding Maddie's notebook, Edgar interviews Vasquez, who reveals she and Maddie interviewed Dockweiler. After Mank agrees to discreetly give him information on the case, Bosch gets a call about a corpse matching Maddie's description being found, but it isn't her. Mo tells him Maddie received a call from a burner phone, and a few calls from Chandler. He visits Chandler, finding she went to see Maddie and saw a man smoking outside, and has her see a sketch artist to describe the smoker. Meanwhile, Dockweiler brings Maddie to the desert and drugs her. Chandler expresses concern about Bosch to Mo, and Dockweiler is shown to have a contact in the police. Edgar and Bennett investigate Dockweiler's house, and find he is a smoker, but he sees them leave. They later match the sketch to a picture of Dockweiler from Maddie's body camera. In Bosch's presence, Chandler tells them Dockweiler was the smoker, and Bosch has Edgar discreetly give him the man's address. He goes to the inspector's house, but Dockweiler tricks him and escapes. Bosch investigates but leaves when Edgar texts him that the police are coming. After he leaves, Edgar calls him and reveals Dockweiler has turned himself in. However, Dockweiler refuses to tell them where Maddie is without a lawyer. Meanwhile, Maddie is shown buried in a coffin in the desert.

In the coffin, Maddie wakes up. Dockweiler agrees to give up Maddie's whereabouts in exchange for immunity. Hearing about this, Bosch asks Edgar to test his boots, based on evidence he found at the house. Crate and Barrel tail Dockweiler's lawyer, James Rafferty. Mo informs Bosch that Dockweiler wiped most of his hard drive, but left evidence that he searched the dosage of sedatives needed to knock out a human for four to six hours, before hacking his account activates an untraceable video link to a camera filming Maddie in the coffin, which is sent to the police and the media. Bosch tricks his way into meeting Dockweiler, and threatens him when he taunts him about escaping the house, but is stopped by Edgar, who covers for him and tells him the results of testing the boots, causing Bosch to realize Maddie is in the desert. Bosch asks Mo to inform Chandler about Rafferty and meet him at his office, and Edgar to investigate if Dockweiler has connections in law enforcement. Maddie starts running out of air and remembers seeing a plane before being tranquilized. Chandler informs Bosch that Rafferty is connected to Dockweiler, while Vasquez joins Mo at the office, witnessing Maddie carve something the letters EDW into the coffin. When Bosch arrives, he identifies it as Edwards Air Force Base, and asks Mo to get the flight paths for recent missions there. When a scorpion gets into the coffin, Maddie kills it, but notices the coffin slowly filling with sand. Chandler distracts Rafferty while Bosch breaks into his hotel room, finding evidence that he legally handled Dockweiler's adoption from a cult in the desert. Mo uses the cult's original location and the flight path data to narrow Maddie's location down to three square miles, and Chandler arranges for a helicopter to take them there. At the location, Bosch and Chandler find the computer sending the video signal, while Edgar interrogates Dockweiler, and realizes from a comment that he buried Maddie. He informs Bosch, who finds a tube buried in the sand. He digs around the tube and unearths the coffin, finding Maddie inside.

A city manager, Alexandra Parks, is found brutally murdered by her husband, sheriff's deputy Vince Harrick. Four months later, Maddie is struggling to overcome her trauma. Bosch decides to restore his house himself. A man named David Foster is arrested for Parks' murder, and asks Chandler to represent him. Chandler is questioned by the FBI about Carl Rogers. She tells Bosch, who realizes they are the only ones involved who are being investigated and someone they worked with gave the FBI information. He asks Mo to look into Chandler's firm, while he confirms that Crate and Barrel have not given up any information and will plead the Fifth if questioned. Chandler questions Foster, but his alibi is not good, and she later discovers that his DNA was found at the crime scene. Mo discovers that an email of the shipping container Rogers attempted to escape in was sent from the firm to the FBI, and he and Bosch discover that Ramirez is the mole. Bosch tells Chandler, and they decide to try to feed him false information. Chandler hires Bosch to work the Parks case to maintain his attorney-client privilege. Two men blackmail a man they record having sex with a prostitute. Bosch discovers Parks' killer may have known her personally, while Chandler discovers Foster's alibi is a lie and that he is using drugs, and he gives her the name and contact information of his dealer. The FBI subpoena Bosch. James Allen, a prostitute and Foster's dealer, is picked up from a hookup and taken by someone he recognizes. Chandler agrees to get Bosch an interview with Foster, while the FBI decide to try to wiretap Bosch. Maddie, meanwhile, now on desk work, investigates a burglary, finding the thief and recovering the stolen valuables, impressing her superiors. She tells Paulina she didn't know when it would be right to come back, but eventually found her footing. At home, she sees Bosch working the Parks case and asks to see the pictures. He reluctantly allows it, and she realizes she is lucky she survived. He offers to help her with her statement for Dockweiler's sentencing, and admits he is working the case because it is similar to hers. In bed, Maddie is shown to sleep with a gun under her pillow.

To Bosch's displeasure, Maddie moves out, moving in with Rico Perez, though they decide to keep their relationship secret. Working the Parks case, Bosch discovers she seemingly had no enemies, while Chandler is unable to find Allen, but gives Bosch information he can use to find Allen's last address. When he goes to it, he discovers Allen is recently deceased and the detectives who worked the case are Rondell Pierce and Christina Vega, his old colleagues. They tell him Allen was strangled, possibly by a serial killer. The FBI continues to investigate Chandler, while Mo hacks Ramirez' phone to monitor all his communications. Maddie is promoted to the CRU, and Mank informs Bosch about this, while she struggles with her statement for Dockweiler's sentencing. She celebrates with her coworkers, including Paulina, who is still not ready to return to work. Bosch and Chandler reconvene and are concerned about the case, and are observed by the two blackmailers, who are revealed to be detectives. When they leave, the detectives split up to follow them, and they discover Bosch's identity and arrange for Chandler to be arrested for a DUI, though she manage to avoid a substance test. The next day, Chandler is released by Mank, while Bosch and Rose meet with Foster and tell him about Allen's death, upon which he admits that they had a six month long affair. Bosch picks up Chandler and tells her about the alibi, but they discover when picking up her car that it was opened after she was arrested and that someone looked at Foster's file. The FBI discovers Chandler was at Wakefield's house after he was killed and took his phone.

The blackmailers plant a tracking device on Bosch's car. Bosch tells Mo he believes Parks wore a watch that wasn't reported in the murder book. He investigates Parks' house, finding a receipt for the watch, and is accosted by her husband, who also informs him the watch was sent to be repaired. Bosch and Chandler investigate the hotel room Allen used, and find he and Foster were indeed a couple, and a picture missing from the room, which may have provided the wire used to strangle Allen. They also get a video showing the entrance to the hotel which shows a vehicle matching Foster's van was at the hotel at the time Parks was killed, though it does not show the driver or the plate number. Chandler tells Bosch she believes she saw the detective who arrested her earlier in the restaurant, while the blackmailers observe them. Meanwhile, on her first day, while Maddie still struggles to cope, she and Vasquez lose sight of a potential thief. Bosch congratulates Maddie on her promotion, while the blackmailers are shown to be using a jewelry shop to fence stolen goods. Mo attends a hacker's conference and meets a woman, while Bosch is accosted by the original investigators of the Parks case. The CRU catches two suspects, but Vasquez sees Maddie unnecessarily beat one of them and later warns her about this. Ramirez is revealed to work for the FBI to avoid prison. Bosch hears the FBI have taken over investigating Wakefield's murder and informs Chandler. The FBI interrogate Aslan about the pipe, and while he does not recognize Crate, Barrel or Mo, he identifies Bosch as the man who blew up the pipe.

The blackmailers demand more money from a plastic surgeon, Dr. Schubert. Bosch and Chandler confront Ramirez, who admits the FBI caught him in a lie and he told them about the blueprint and Wakefield's phone. They ask him to keep them informed about the case. Chandler is summoned to a hearing to have Bosch removed from the case. At the hearing, Bosch is not removed, but the judge pressures Chandler to have Foster plead out. Bosch asks Mo to look into Parks' calls to find anything about the watch. Meanwhile, Mo starts a relationship with the woman he met at the convention, Jade Quinn, and hears her ex-boyfriend stole her family's medical information and is blackmailing her with it. He plants a device in the company that has it, enabling him to get the information, impressing her. Bosch investigates Allen's murder, finding out from Pierce and Vega that he may have turned informant three years ago, that he didn't struggle when strangled and his personal affects were taken from his room. He later discovers the body was dumped by two people, and informs Chandler, also asking her to test the semen for CTE. Chandler convinces Foster not to take a deal. They then find out where Allen's things are, and Bosch discovers Allen was killed by someone he recognized, in a car similar to the car that dumped the body. Meanwhile, Maddie is asked to give a statement at Dockweiler's sentencing, and struggles to come to terms with being a victim, but is consoled by Chandler. At the sentencing, she affirms her survival and condemns Dockweiler, pleasing Bosch and Vasquez, though Perez becomes concerned about her moving out. Mo tells Bosch who Parks called about the watch, and Bosch decides to investigate himself. He visits the jewelry store, and realizes the owners are hiding something. As he leaves, he is shown observed by the blackmailers, who respond by killing the owners and staging it as a robbery.

The blackmailers contemplate killing Bosch while keeping tabs on their competition. Chandler mails a letter, while Bosch investigates the watch, finding it was sold by the original owner, Dr. Schubert, but he lied to his wife that it was stolen to avoid her finding out about his gambling debts, and gets the doctor's number. Mo hacks the pharmaceutical company and gets Jade's information, later giving it back to her. Bosch is contacted by the police about the murders of the jewelry store owners, and brings Chandler to his interview, where they find the owners were killed in what looked like a robbery shortly after he left. Chandler shuts down the interview, but Bosch tells them about the watch, afterward telling her the killers may be watching them. Paulina returns to work, while Maddie is interviewed about her statement and later becomes emotional in front of her friends. The blackmailers investigate Bosch's house, finding Maddie is his daughter. They later give evidence of their competition to their handler, asking for the CRU's help in bringing them down. The letter Chandler mailed arrives at the LA Times, publicizing the information on the investigation into her, causing the grand jury to be delayed due to the Bratva's involvement. Bosch tells Maddie about his progress in the case, and later finds a recorded conversation between Parks and the jewelry store owners revealing she knew the watch was stolen. He is later informed by Pierce about the names of Allen's handlers, Ellis and Long. When Mo tells him the two have a history of surveillance, they find the bug on his car, but leave it. When arresting their competition, Ellis and Maddie are left alone, and he tricks her into revealing details about Bosch's progress in the case. She then sees him beat the suspect, but he convinces her not to report it. Chandler gets Allen's belongings and tells Bosch and Mo that Ellis and Long were the ones who arrested her. When she hears the recorded conversation, Bosch and Mo return to the jewelry store to look for proof of the watch being stolen. Ellis and Long observe them, having realized Bosch has found the bug. At the store, Bosch and Mo find a DVD. As they leave, Ellis and Long follow them, and accelerate toward their car.

Ellis and Long run Bosch and Mo off the road. In the hospital, a concussed Mo tells Bosch the car was silver, and loud, like the car used to dump Allen's body. The FBI get a warrant for Chandler's property, while Bosch, knowing he is compromised, destroys the bug. Bosch shows Chandler the DVD, footage of Ellis and Long threatening the store owners. He then finds the car at the body shop, and takes evidence from it. Chandler gets more video of the hotel entrance and is told about the warrant by Ramirez, who the FBI has realized is compromised. Maddie is interviewed by the FBI and learns about the pipe. She meets her father, but is upset when he doesn't tell her about it. Ellis and Long find out Bosch examined their car. Jade helps Mo recover, and he shows her the video he enhanced. Chandler has Foster moved to protective custody after he is beaten in jail, and she and Bosch view the video showing Ellis and Long's car at the hotel the night of Allen's murder. Bosch tells Chandler the FBI questioned Maddie, and she attempts to reassure him, while Ellis and Long decide to shut down their operation. Mo observes Ellis and Long's prostitutes with a client, while Bosch confronts Dr. Schubert at his house, recording him admitting he slept with a patient, and Ellis and Long blackmailed him with a video of it. Ellis and Long arrive, recognizing Bosch's car. Bosch attempts to protect the doctor, but he tries to surrender. Long kills him, and Bosch shoots Long. Ellis flees as the police, called by Bosch, arrive. After Long refuses to talk and is moved to the hospital, Bosch gives the recording to the police, who refuse to take it as evidence of anything. Afterward, he asks Chandler to set up the two prostitutes, who can testify to the extortion, at a safe house. When he meets Maddie, she admits she worked with Ellis and told him details of the Parks case. He tells her he would never lie to her. The FBI arrive at Bosch's and Chandler's homes and offices and find a recording of Chandler threatening Rogers after the pipe was blown up. Using this as evidence, they arrest Chandler.

The FBI attempt to intimidate Chandler into taking a deal, but fail. Maddie reprimands her father about not taking protection and asks him what he has planned, but he is evasive. Ellis, hiding on a yacht, obtains a fake ID and arranges for a car, later taking a man hostage when he checks in on the boat. Chandler is bailed out by Rose and gives a statement to the media that she is being harassed, which is seen by the FBI, and Mo, who is watching the two prostitutes at the safe house. Chandler and Bosch give their findings in the Parks case to the DA, who refuses to accept it, and they realize he is avoiding admitting Foster is innocent due to the political embarrassment it would cause. At Chandler's hearing for the Rogers case, Chandler gets the charges against her dismissed by showing the FBI's probable cause was false, though Agent Barron, the lead agent in the case, warns her and Bosch they are not done. Leaving the courthouse, Bosch is tailed by someone and attempts to lose them, but it turns out to be Maddie when he is pulled over, and she tells him the CRU is watching him due to his refusal of protection. Mo tells Bosch the prostitutes are getting restless, and he tells Chandler, losing the police on his way to meet her. Maddie expresses her concerns about Bosch to Vasquez. The prostitutes reveal that Ellis and Long once blackmailed a man who gave them a boat, which Bosch uses Mo to track down at a marina. Maddie and Vasquez find where he is and head go themselves. At the marina, Bosch gets onto the boat and finds the captured man but is caught by Ellis. He fights back, and the commotion attracts Maddie and Vasquez, which culminates in Maddie shooting Ellis when he points a gun at her father, causing him and the gun to fall in the water. Bosch thanks Maddie, who expresses nothing. Jade Quinn is revealed to be an undercover FBI agent, Janice Morrell, and Barron tells her to "move" on Mo.

Maddie gives a statement to the police and is worried when she is told that they haven't found Ellis' gun yet. She later tells her father she is angry with him for putting himself in danger. Chandler finds out Aslan is no longer cooperating with the FBI and is given the results of the CTE by Ramirez, but doesn't let him continue working for her. Morrell admits to Barron that she is becoming attached to Mo, even though they are planning to get him to give up Bosch and Chandler. Chandler tells her therapist she can live with what she has done. Bosch is informed that someone in prison was assaulted. Mo is arrested by the FBI, while Chandler presents the CTE and is allowed to argue third-party culpability at the trial. The FBI attempt to intimidate Mo, eventually giving him a week to turn in Bosch and Chandler. Maddie tells Perez she has found a place and is moving out, while Bosch and Chandler decide to get a confession from Long. Bosch tricks Long into confessing, but the confession is not taken as evidence by the DA, so Chandler threatens to release it to the media unless he drops Foster's charges. Afterward, she meets Irvin Irving, former chief of police, and asks him to endorse her for DA. The DA drops the case, while Maddie is informed that Dockweiler is dead, which Bosch tells her to let go.
