F.I.R.

Roy Alex, an investigative journalist, publishes a piece on hawala money flows from the Middle East. This leads him to cross paths with Rahim Haji, a former MP and business tycoon, invited by Haji's driver Basheer. Haji explains that foreign reserves are concentrated along the Gulf-American belt, and proposes collaboration to revive his business.

Haji lays out his plan to revive his faltering business and to eliminate Narendra Shetty, whom he blames for his downfall. He sees Roy as an ally because of his investigative skills and media influence, hoping to leverage Roy's reach.

Roy follows a van carrying a drama troupe to a remote residence where a businessman and Chakrapani, the drama director, press for black money payments. He manages to capture the illicit funds as evidence, exposing the scheme.

Chakrapani locates Roy and kills him using his guard dogs, ending Roy's disruptive presence and his investigation into the black money dealings. The death removes a key obstacle in the criminal network's exposure.

News of Roy's death reaches Rahim Haji, who immediately seeks out Narendra Shetty to challenge the criminal empire. He trespasses into Shetty's territory, but Shetty fatally shoots him, delivering a major blow to Haji's faction and his political influence.

Basheer, Haji's driver and ally, betrays him and aligns with Narendra Shetty. This betrayal undermines Haji's plans, weakening his position and complicating the political and criminal turf war.

The assassination of Rahim Haji delivers a severe blow to his party and its leadership. The loss creates political turmoil and heightens the urgency of the investigation into the murders and the broader criminal network.

Chief Minister Nair appoints Mohammed Sarkar, an IPS officer from the Tripura cadre, as the Superintendent of Police to investigate the assassination. This signals a formal, high-stakes pursuit of the culprits and a shift in investigative leadership.

A fast organized by MLA Kunjalavi sparks a major rift between police officers and party workers. The protest magnifies the political discord and poses challenges to law enforcement during the investigation.

Sarkar interrogates Chakrapani and Basheer, extracting crucial testimony and gathering evidence that points to Narendra Shetty as the central orchestrator. The accumulative evidence strengthens the case as the investigation progresses toward a confrontation.

In a climactic confrontation, Mohammed Sarkar shoots and kills Chakrapani, dismantling a key node of the black-money operation. The killing marks a turning point in the pursuit of the gang's remaining members.

Narendra Shetty makes a desperate attempt to assassinate Sarkar, but is thwarted. During the ensuing confrontation, Gurumoorthy is killed, escalating the stakes for Sarkar and heightening the resolve to finish the case.

Enraged by the losses and the ongoing conspiracy, Sarkar destroys the warehouse that harbored their criminal operations, killing Narendra Shetty and Brigadier Giridhar Baruva in the process. The warehouse's destruction brings the criminal network to a decisive end.
