In Chennai, Thirumaaran works as a financial analyst for Vahjra Motors, a company that manufactures heavy vehicles. The firm unveils one of the world’s highest-mileage trucks, sending its stock and profits soaring in the markets. But the gleam hides a dark secret: Ved Tiwari, the company’s Mumbai-based CEO, knows the trucks emit dangerous pollutants and chooses to bury the truth to protect profits, keeping it hidden from the 18 board members and 20,000 employees. When the cover-up begins to surface, the entire operation is put at risk, and the tension inside the company becomes impossible to ignore.

To silence the whistleblower, Ved Tiwari hires Arjun Arjun — a former commandos turned private investigator — who pursues the leaks with ruthless methods. As he digs, Arjun uncovers a broader web of insiders working against the company and zeroes in on Jayaprakash (JP) in the Chennai regional HQ, Jayaprakash. He coerces a confession by showing JP’s granddaughter being assaulted and reminding him that his son committed suicide after witnessing the video. JP eventually confesses that he does not know the whistleblower by name, but he reveals that Vahjra is involved in covert corporate maneuvers that take government factories away from workers and that other whistleblowers have exposed international conglomerates in the past.

Using CCTV footage, Arjun tracks down Thiru’s friend Gandhi / Karthik, Gandhi / Karthik, and the pursuit leads to a brutal confrontation. The man posing as Karthik is unmasked as a fraud with bogus identity papers, and a surgical scar spurs the hospital inquiry. Arjun learns that Thiru is the actual whistleblower and searches for Thiru’s guardian, Bharathi. Bharathi’s subsequent suicide shocks Arjun, while the investigation deepens to Thiru’s ex-girlfriend, Maithili. Maithili Prasad becomes a crucial anchor in the case, and Arjun manages to locate Thiru and bring him to an abandoned chemical factory, intending to end the matter. But Thiru fights back, overpowering Arjun and his associates, turning the tables in a way that reveals deeper stakes than personal vendetta.

What follows is a reveal of a layered, tragic past: Thiru’s parents, Gandhi’s father, and Bharathi’s husband were all chemists who worked in that same abandoned factory, a site later purchased by the Vahjra factory. They had learned about the chemical pollutants leaking from Vahjra’s operations and filed complaints, only to be killed by Ved Tiwari and the corporate machine. This history fuels Thiru and Gandhi’s decision to blow the whistle on Vahjra’s illegal activities once again. The next day, Ved Tiwari dies of a stroke after learning that their deal with TVG, a German startup, has been sold to a Russian mafia outfit. The truth behind TVG’s chairman is Velmurugan, Velmurugan, whose positioning is revealed as part of a larger plan to bring down Vahjra. With the government stepping in, Vahjra’s operations are shut down, and the scramble of corporate power ends in public exposure rather than quiet escape.

Six months later, Thiru moves on to another company but continues his work as a whistleblower, ensuring that illegal practices are brought to light and that accountability remains in focus. The story closes on a note that resilience and vigilance can lead to systemic change, as Thiru remains dedicated to exposing wrongdoing and protecting people from the harmful consequences of polluted, deceitful corporate practices.
