At the start, a group of women from Selva's village attempt to cross a fast-flowing river in torrential rain using a rope. The crossing ends in tragedy as they drown, signaling the reach of violence in the region. This event hints at a larger context of corruption and stolen money driving the conflict.

Two masked men shoot two men inside a car, then kill two more, and finally shoot another man. The killings appear coordinated and point to an organized network rather than random crime. Deputy Commissioner Shakthi begins tying the murders to a larger conspiracy.

Deputy Commissioner Shakthi takes on the murders and starts connecting the dots. He deduces that a Russian-made pistol was used, suggesting a specific supplier or group. The discovery links the killings across different locations and launches the central investigation.

Selva moves in with Karukkavel and becomes entangled with Sara. He works as an assistant manager at IBCI Bank, placing him in proximity to the money flow and the powerful figures who control it. The budding romance complicates loyalties as the case deepens.

Investigations reveal that the men who died had connections with Rajavel, a minister. Shakthi learns that criminals killed convoy members on a train and looted ₹230 crores meant to be distributed to area rowdies. Rajavel asks Shakthi to locate the missing money, raising the political stakes.

Selva proposes to Sara, testing their bond. Shakthi redoubles his efforts as another murder occurs at a hotel with theft involved. The pattern of crime swells into a broader plot linking money, politics, and vengeance.

A plan to move ₹150 crores by train is foiled when a scuffle leads to theft and Selva is shot in the arm by Nallathambi's men. The incident exposes the fragility of security and deepens the personal risk for Selva. Shakthi grows more determined to clean up the corruption.

Shakthi visits Selva in the hospital and thanks him, concluding that most people in the train compartment are thieves. Selva's friend warns villagers to evacuate with the money, while Sakthi orders a camera to be planted in Selva's room and searches for the gun in his suitcase. Rajavel pressures Nallathambi to kidnap Selva and retrieve the money.

Sakthi's men interrogate relatives and learn that Sara's father Isaac was murdered in an accident the previous year. Selva tries to win Sara's trust through her aunt, while Sakthi manipulates Sara to coax Selva into confessing. The revelations tie current crimes to a broader conspiracy and personal vendettas.

Rajavel scolds his brother to secure funds for his election and reveals another ₹100 crores coming from quarry owners. The escalating money flow deepens the corruption, making it harder to separate crime from politics. Selva continues to resist arrest and fights Nallathambi's men.

STF surrounds a building and Sirisu shoots at the STF team, revealing a traitor among Varadhan's men. The SPF team and Sakthi respond by eliminating Nallathambi's men. In the climactic struggle, Nallathambi wrests Selva's gun and accidentally shoots Sakthi in the shoulder.

Selva escapes with ₹100 crores after the chaotic showdown, while Sakthi kills Nallathambi. Shakthi visits Kumananthozhu and sees a new bridge being built by Selva and the villagers. Selva proclaims that the money is black and that the gun belonged to Nallathambi, implying he cannot be arrested.
