SSP Vikram is an honest police officer, who has a black-and-white sense of good and evil. Vedha Betal is a dreaded gangster from Kanpur who understands the nuances in between. Vikram's best friend SSP Abbas leads an encounter unit in the STF, which is formed to eliminate Vedha. In one encounter, the squad kills some of Vedha's henchmen, framing an unarmed criminal killed by Vikram to avoid further inquiry. As the unit plans another encounter, Vedha enters the police station and voluntarily surrenders. When Vikram interrogates Vedha, he offers to narrate a story to him, which moves to a flashback.

Act 1: Chor-Chor

Vedha is a henchman to dreaded criminal kingpin Parshuram Pandey; he warns his younger brother Shatak, a mathematical genius, to stay away from crime, but Shatak is forced by a rival gangster, Babloo to carry drugs. When Shatak and his friend Chanda are caught by the police, Shatak confesses and Babloo is arrested. On his boss Shiv Prasad's orders, Babloo assaults Shatak, leaving a permanent scar on his hand.

Present Day

Vedha asks Vikram if he should kill Babloo or Shiv Prasad. Vikram replies that Shiv Prasad was the real culprit, to which Vedha implies that he killed Shiv Prasad. Vedha's lawyer, who turns out to be Vikram's wife Priya, intervenes and bails him out. Vikram realises that the unarmed criminal framed by them for avoiding inquiry was actually Shatak, based on the mark in his hand. Worried that Vedha might try to kill Abbas out of revenge, Vikram rushes to save Abbas, but finds him and Chanda shot dead. The IG dismisses it as a botched encounter. Priya refuses to divulge Vedha's whereabouts to Vikram. Enraged by this, Vikram raids Vedha's tenements and manages to capture him. Vedha requests Vikram to listen to another story.

Act 2: Chor-Chorni

Shatak, now grown-up, offers to launder Vedha's income by investing it in shares. Pandey invests INR 1 crore (US$120,000) in this venture. However, Chanda is supposedly kidnapped and the money is missing. Chanda returns and reveals that she stole the money to start a new life, but came back because she loves Shatak. Vedha returns the money to Pandey, who orders him to kill Chanda.

Present Day

Vedha asks Vikram if he should respect Pandey and carry out the order or disobey him and support Shatak and Chanda, thus inciting a gang war. Vikram replies that he should support Shatak to which Vedha agrees. Realizing Shatak's innocence causes Vikram to stumble momentarily, at which point Vedha attacks and subdues him to escape, albeit not before telling him to investigate Shatak's and Abbas's deaths.

Vikram begins his investigation with Abbas's informant, who led them to Shatak's hideout, but finds that the informant has been killed. He and his unit try to find the killer. Vikram takes a moment to recollect when he finds the leader of the Mumbai Gang from Vedha's story. He apprehends and fights him only for the gang leader to almost kill Vikram before getting shot and killed by his unit member Deepak. Vikram searches his room, but finds a cigar where he finds that the cigarette is filled with marijuana instead of tobacco. Vikram deduces that Babloo is behind the encounter and informs Vedha at his restaurant, who brings Babloo to an abandoned factory. Vikram arrives and meets Vedha, who kills Babloo, leaving Vikram frustrated on being unable to determine Abbas' killer. Flustered, he threatens Vedha, who asks him to patiently listen to the third and final act.

Act 3: Chor-Police

Vedha has since become a tour de force in the lanes of Lucknow, having sent Shatak and Chanda away to Mumbai since the feud with Pandey. He noticed that only his men, except Pandey's, are being targeted and eliminated by the cops. Among the few surviving men in his company are Babloo and his right hand man Sanki. During one such chase, Sanki pushes Vedha out of their vehicle, only to be intercepted by a cop, revealed to be Abbas; in a twist, it is revealed he is on Babloo's payroll.

Present Day

Vedha asks Vikram if Abbas was right, since he became corrupt to pay for his son's medical procedure. Angry at himself for failing to judge his best friend's circumstances, Vikram shoots bullets to the ground in frustration even as Vedha casually walks away. As the unit arrives later, the IG castigates Vikram for letting Vedha escape again. Vikram slowly realises that the entire unit had also been bribed by Babloo. The IG reveals that Babloo paid them to kill Vedha and Chanda's abduction was intended to lure Shatak out of Mumbai, which would lure Vedha out of hiding. However, a guilt-ridden Abbas had gone to save Chanda, but the unit had killed them both. As the unit prepares to kill Vikram, Vedha reappears and saves him. A gunfight ensues, and Vikram disables all his colleagues with Vedha's help, but kills the IG. Vikram asks Vedha if he should let him go for saving his life or kill him since he is a criminal; a standoff ensues between them.
