Die Hard-inspired alien terrorists attack the Blips and Chitz arcade and cause a temporary power outage. As a result, Morty becomes trapped in the virtual reality game Roy, with his identity split among the game's five billion NPCs. Rick enters the game, playing as the titular Roy, to try to convince the NPCs that they are part of Morty. Rick builds millions of spaceships, planning on taking all the fragments to the edge of the map, which will reset the game and allow Rick and Morty to exit. However, Rick faces resistance from many Morty fragments, some of whom go to war with each other. One individualistic fragment, Marta, negotiates with Rick—she will convince the other Morty fragments to leave on one unspoken condition. Meanwhile, Summer picks off the terrorists, led by Chans, one by one. Chans explains that all sapient species develop the Die Hard mythology and that he is an expert who has written several books about it. Summer reads one of Chans' books, then defeats him with a gun taped to her back just as Rick and Morty escape Roy. Rick pays a Blips and Chitz staffer to take the still-running Roy machine into storage, with Marta left behind inside.

Post-credits scene: An alien stands outside a snow base wearing a sandwich board that says "I HATE EVERYBODY". Two other aliens watch from afar and debate whether the sign's message is too broad to provoke anyone.

Space Beth comes back to celebrate Thanksgiving. She and Beth bond over a bottle of Venusian Wine which Space Beth had brought back from Venus. Eventually, their casual flirting develops into a full-on love affair. Summer and Morty notice, but try to ignore it by playing "realistic" alien video games. Rick deduces the affair after he and his grandkids catch them pulling a "San Junipero" in his holodeck. Rick tells Beth that while he once did something similar, she must be careful about what this could do to the family. Summer and Morty become concerned about Jerry, who previously claimed he would kill himself if Beth cheated on him. When Space Beth admits to the affair to Jerry, he rolls up into a pillbug (an emotional defense system Rick built for him while they were drunk together). Both Beths ask Rick to erase their memories of the affair. Jerry overhears this and exits his pill bug form to stop the erasure, but says he is leaving Beth. Space Beth realizes that Jerry is only upset that the affair happened without his knowledge. With Jerry's full consent, he and the Beths have a threesome, to Summer's and Morty's disgust. After Space Beth leaves, Rick locks the Venusian Wine in an invisible cabinet and destroys its key-remote.

Rick obtains an alien device called a "somnambulator" that allows him to voluntarily sleepwalk, creating a "Night Person" who does tasks that he does not want to do in the daytime. The rest of the family create their own "night people" who exercise, learn new skills, and do household chores. Eventually, Night Summer leaves a note requesting that Rick rinse the dishes before she washes them, but Rick deliberately ignores the request. The escalating conflict between the Smiths and their "night family" over the dishes ends with Night Summer and her minions locking Rick out of his own technology, building a giant version of the somnambulator to maintain permanent control of their bodies, and enslaving their diurnal selves while the Night Family sleeps. The Smiths attempt to escape with the help of Night Jerry, whom Jerry had befriended by leaving handwritten notes for him, and a chaotic battle ensues as both sides fight for control by tranquilizing and waking each other. Night Summer offers a truce in exchange for Rick washing his dishes. Rick refuses and as a result, Summer allows his Night Person to retake control of his body.

Jerry receives a fortune cookie that says he is destined to have sex with his mother. Upon noticing how circumstances seem to be moving inexorably toward said fortune, he and Rick infiltrate the fortune cookie factory to investigate while Morty, Summer, and both Beths visit the zoo. There, the two find that fortune cookies come from the excrement of a captive fate-altering alien called a Lockerean, and Jerry's fortune came from its imprisoned caretaker in an attempt to draw scrutiny. CEO Jennith Padrow-Chunt brings in a squad of armed fortune-boosted guards, alongside Jerry's mother to ensure he follows through with his fate, until Rick feeds Jerry another fortune cookie that cancels it out at the last minute. Because people are immortal until their fortunes are fulfilled, Rick finds a way to make Padrow-Chunt the world's most successful businesswoman (her fate), thus rendering her vulnerable, and she and the caretaker are subsequently eaten by the Lockerean. After they return home, it is revealed that Rick survived by eating a fortune that said "You'll make a new friend", which Jerry accidentally fulfills by thanking him and calling him a friend, much to Rick's chagrin.

A technologically advanced species of dinosaurs arrive on Earth, stating that it is their former home and they travel between worlds to spread peace and technology. The world's governments grant them control and they soon make work obsolete and create a utopia. Many people, however, are dissatisfied with the lack of responsibility, including the President, who promises to let Rick host the Academy Awards if he can get rid of the dinosaurs. Rick and Morty visit other planets that the dinosaurs have tended, finding that they all suffered asteroid impacts similar to the one that caused the Chicxulub crater. Rick announces that dinosaurs have a rival species of homicidal sentient asteroids, one of which is headed for Earth. Reluctant to use violence even in self-defense, the dinosaurs leave to draw the impactor away. Rick hosts the Oscars, but leaves when Summer tells him the dinosaurs are on Mars awaiting their demise. He travels to Mars and tells the dinosaurs that selflessness and selfishness are the same, prompting them to destroy the asteroid. In thanks for Rick "saving" them, the dinosaurs fix the temporal rift, much to his dismay. Rick returns home and repairs his portal gun, excitedly telling Morty their interdimensional adventures can resume.

After venturing beyond the fourth wall into the meta where all fictional characters exist, Rick and Morty fall into a trap set by Story Lord from "Never Ricking Morty". Story Lord steals Rick's device which allows him to travel to the real world and seek out his creator, Jan. Meanwhile, Rick and Morty, seeking a way back to the real world, infiltrate the fortress of the "Self-Referential Six", a group of "meta nerds" who all have reality-warping powers based on narrative techniques and devices (such as plot twists and continuity errors), but are attacked by the group and forced to flee back into the meta. They are rescued by Joseph Campbell, who assists them in creating a device to return to the real world to confront Story Lord. Jan and Story Lord have created a machine capable of siphoning motivation from the universe's inhabitants to fuel Story Lord's own "motivation." Morty, with the assistance of a spectral Campbell, convinces Jan to stop operating the machine, depowering Story Lord and allowing Rick to defeat him. At Morty's and Campbell's prompting, Jan kills Story Lord. After Rick and Morty depart, he becomes inspired to continue writing, much to the spectral Campbell's dismay.

Tired of attacks from supervillains, Rick goes to Dr. Wong from “Pickle Rick" for advice. She recommends that he ignore them. A villain named Pissmaster goads Rick into battling him, which Jerry does in his place when Pissmaster makes a sexual remark about Summer. The incident goes viral and Jerry is invited to sit on a council of intergalactic superheroes, much to Rick's jealousy, until Dr. Wong points out that Rick is now free of burden. Rick is happy at first until he discovers Pissmaster committing suicide, having left a note blaming Jerry. Rick dons Pissmaster's suit and performs many heroic deeds, redeeming the villain's public image. The council sends Jerry to offer Pissmaster a seat among them, which Jerry reluctantly and forcefully attempts to do as Rick disarms a bomb by sacrificing Pissmaster's suit to cover his suicide with a heroic death. The council dismisses Jerry for his arrogance. Rick lies that he was Pissmaster all along to make Jerry feel better about himself, but secretly gives Morty the real Pissmaster's suicide note. Horrified, Morty promptly tells the rest of the family, who berate Rick for his actions and shame Jerry for Pissmaster's death.

Morty refuses and attempts to leave; opposed by the King of the Sun, he bests the King in combat and becomes King himself. He exposes the Knights' worldview as flawed and convinces them to disband. Without the Knights' influence, a peace summit among the leaders of the planets fails and a war breaks out. Morty finds the Knights of the Sun using heroin and inspires them to resume their duties by promising he will cut off his penis, Rick having built him a fake.

For Christmas, Rick gives Morty a working Star Wars lightsaber, which he accidentally drops perfectly vertically. This causes it to tunnel into the Earth, threatening to destroy the planet if it reaches its core. Morty learns that Rick replaced himself with a robot after Morty had called him "boring" in "A Rick in King Mortur's Mort", while the real Rick is busy with his search for Rick Prime. During their quest, Morty is aided by the President who then steals the lightsaber. The President accidentally drops the lightsaber in the same manner, forcing Morty and Rickbot to retrieve it. In the ensuing confrontation with the President at the White House (which the President launched into outer space to escape the possible destruction), Rickbot is mortally injured and the three are sucked into space, but Rick rescues them with a portal. Rickbot succumbs to his injuries and tells him he was only doing what Rick would have done in his place. As the President takes his leave, Morty joins Rick in his underground lab, offering to help him locate Rick Prime, prompting Rick to monologue about their impending arduous efforts to track Rick Prime during the upcoming season 7.
