Sumair Azad, Shahid Kapoor an NCB officer, and his deputy Jagadish Prasad alias Jaggi, Zeishan Quadri operate in Gurgaon and bust a drug deal that sends shockwaves through the city. The operation draws the attention of Sikandar Chowdhary, a feared drug lord Ronit Roy, who responds with a ruthless gambit: he kidnaps Sumair's young son, Atharv Azad Sartaaj Kakkar, and demands the return of a bag of cocaine in exchange for his child's safety. What begins as a routine seizure quickly spirals into a high-stakes game of trust, deception, and latent loyalties.
To secure his son's safety, Sumair agrees to retrieve the bag from the NCB headquarters and deliver it to a club for the exchange. He hides the bag in the men’s toilet, a move that his assistant notices, triggering a tense chain of events. Aditi Rawat Diana Penty, Sumair’s sharp-eyed aide, spots the suspicious act and alerts her superior, Sameer Singh Rajeev Khandelwal. What starts as a routine investigation quickly escalates as Aditi and Sameer close in on Sumair, dismantling the initial setup piece by piece and seizing the bag of cocaine from the toilet.
Desperate to salvage the situation, Sumair proposes a risky bluff: he returns a bag filled with flour, hoping Sikandar and his cronies will not notice the difference. The plan backfires when Sikandar, aided by his trusted ally Hameed Shaikh Sanjay Kapoor, discovers the ruse. The realization sparks a deadly pursuit, with Sikandar and his men moving to eliminate Sumair. Caught between Sikandar’s gang and the authorities, Sumair is forced to make a pivotal confession: he has been undercover all along, working to expose the collusion between Sameer, Jaggi, and Sikandar in drug smuggling.
In a dramatic turn, Sumair manages to rescue Atharva without Sikandar’s knowledge, turning the tide in favor of the undercover mission. Sikandar is eventually arrested by Aditi and Sameer, bringing a measure of justice to the dangerous web they have navigated. But the investigation uncovers another twist: Jaggi’s mobile phone, hidden in Sumair’s jacket, contains messages that corroborate Sumair’s claims and reveal the depth of the conspiracy involving Sameer and Jaggi.
Sameer’s resolve hardens as the pursuit for accountability intensifies. He resists arrest and fatally shoots Sikandar, yet the law ultimately catches up with him as well, restoring a sense of balance to a case built on murky bargains and hidden agendas. The revelation shakes the core of Sumair’s mission, but the work to expose a broader network of drug dealers continues, with Atharva playing a quiet, uneasy witness to the murkier sides of the case.
In the end, Atharva discovers drug packets in Sumair’s car, a shocking sign that Sumair himself may be entangled in the drug trade. The film concludes on a somber note: during the credits, Atharva remains silent about what he has found, choosing to embark on a short trip with Sumair as they face an uncertain future together. The story remains a tense, morally complex portrait of crime, loyalty, and the costs of undercover justice.
