Naina Sethi is a young and shrewd successful businesswoman in London with a perfect family. Her world turns upside down when she gets arrested for the murder of her secret lover, Arjun. Naina's lawyer, Jimmy Punjabi, hires prestigious defence attorney Badal Gupta to defend her, and over the course of one late evening, they work together to find out what actually happened. Badal reveals that there is a witness whose testimony will incriminate her in the crime. Naina explains that she and Arjun were blackmailed by someone for their extramarital affair. They were called to a hotel where Naina was attacked; only to wake and find Arjun dead with the money meant for the blackmailer. She was arrested but is out on bail. The police find no trace of anyone else being present in the room or breaking in.

Badal tells Naina that she is not being honest with him and questions her about the disappearance of a young man near the hotel. Naina reveals that she and Arjun went to a cabin in the woods few months ago. On the way back, she accidentally crashed into an oncoming car and killed its driver, a young boy named Sunny. Arjun convinced Naina not to inform the police, and they removed any trace of the crime. They put Sunny's body in the trunk of his car, which Naina dumped in a swamp. While Arjun was waiting for her, Rani and Nirmal, a local couple, met and invited him to their home, where Arjun discovered that they are Sunny's parents. When Rani called Sunny, his phone rang in Arjun's pocket as he had forgotten to dispose of it, making Rani suspicious. Arjun and Naina get away but become worried that they will be discovered soon.

Naina watched the news showing that Sunny had embezzled money from the bank where he was working before disappearing. She learned that Arjun had taken Sunny's wallet as they disposed of the body and used his girlfriend's employee credentials to hack into the bank to frame Sunny as a criminal. Rani identifies Naina's car at the scene of her son's disappearance, making her a suspect, but Naina has her lawyer falsify an alibi. The police buy it, but Rani is unconvinced. Rani later confronts Naina at a press event and reveals that she knows the truth. She pleads Naina to tell her Sunny's location but Naina keeps up her act of innocence. A few months later, Arjun and Naina are contacted by the blackmailer, leading to the present events.

Badal decides that Rani must have killed Arjun and could have easily done so since Sunny's father, Nirmal, works at the hotel. Naina reveals that she saw Rani in the room but lied to check whether Badal was a good lawyer or not, to which Badal reveals there was no witness and he was lying to get the truth from Naina. However, Naina who now trusts Badal, reveals a secret: Sunny was still alive in the trunk before she disposed of the car. However, she let him drown, deciding not to save him to protect herself from potential incrimination. Surprised by her murderous and selfish actions, Badal proposes an alternate sequence of events in which Naina was the one who actually pressured Arjun into hiding the crime and framed Sunny. In this version, Arjun grew so guilty that he traveled to the hotel to confess the truth to Rani and Nirmal, prompting Naina to kill him. With the police knocking, she decided to injure herself and frame Rani for the crime. Naina denies this and claims that what Badal proposed earlier is the truth.

Badal refuses to fight Naina's case. When she implores him for help, he agrees only if she honestly tells him whether she killed Arjun. Naina confesses to Arjun's murder, revealing where Sunny's body is. Badal agrees to continue defending her and excuses himself for a moment, going out to get some fresh air while Naina receives a call from Jimmy. She realises that Badal's pen is interfering with the call. Naina then discovers that the person who came to her as Badal Gupta was an imposter when she finds the real Badal Gupta at the doorstep. Naina, shocked, takes apart Badal's pen to reveal a voice recorder inside that recorded every word of their meeting, including her confessions of both murders. As she glances outside her window, Naina makes eye contact with the imposter and Rani in the apartment building across from hers. "Badal" takes off his disguise, revealing himself to be Nirmal. Rani calls the police for Naina's arrest.
