Diwakar and his deputy Mani stage a covert theft of a narcotics shipment, hoping to seize evidence. The operation spirals out of control and Diwakar is stabbed, leaving him bleeding as the team scrambles to retreat. The botched heist signals the start of a deadly game with Vittal Rao, a ruthless drug lord watching from the shadows.

Vittal Rao abducts Diwakar's son Vasu and issues a chilling demand: Vasu will be released only if Diwakar returns the cocaine bag. The kidnapping sets a high-stakes trap that forces Diwakar to consider dangerous compromises. Tension mounts as both sides gear up for a confrontation.

Under pressure, Diwakar heads to Vittal's nightclub carrying the bag, hoping to barter for Vasu's safety. Vasu is held hostage inside the nightclub, and Diwakar risks exposure to save him. The clock ticks as loyalties blur and danger closes in.

Diwakar tries to stash the cocaine bag in the men's toilet at the nightclub to hide the evidence. Mallika, an attentive NCB agent, grows suspicious and informs her superior Dhiraviyam. Dhiraviyam moves in and seizes the bag from the toilet as the trap tightens.

Diwakar realizes the bag has vanished and pivots to a risky plan: he swaps it with a bag filled with packets of milk powder. He hopes his cronies, including Pedha Babu, won't notice the substitution. The tension rises as the wrong contents threaten to blow his cover.

Vittal and Pedha Babu uncover the ruse and move to eliminate Diwakar. The pursuit tightens as Diwakar's wound worsens and he is trapped between Vittal's men and Mallika's team. The standoff reaches a breaking point with shots and taunts echoing through the club.

In a tense confrontation, Diwakar reveals that he has been undercover all along. He explains that his mission was to expose corrupt cops like Dhiraviyam and Mani, who smuggle drugs and tried to frame him. The revelation shifts the balance of power at the scene.

Seizing the moment, Diwakar rescues Vasu without Vittal realizing. Mallika and Dhiraviyam close in and take Vittal into custody, ending his hold on the boy. The victory comes with the price of fresh danger as loyalties are tested.

During the ride to prison, Mallika discovers Mani's mobile phone and reads messages that corroborate Diwakar's claims. The messages reveal Dhiraviyam and Mani's involvement in drug smuggling and an attempted frame-up of Diwakar. The corrupt alliance is exposed in a quiet, revealing moment.

Dhiraviyam resists arrest, and in a final act of violence, Vittal is killed. The showdown seals the downfall of the drug network as justice closes in. The officer’s persistence ensures the villains finally face consequences.

Diwakar's wounds leave him unconscious for a while, and Vasu rushes him to the hospital where doctors begin to stabilize him. Mallika and the rest of the team secure the area, ensuring no more threats remain. The immediate danger passes, but the scars of the case linger.

Three months later, Mallika has become Diwakar's deputy, and they continue to fight crime together. They thwart an attempted murder of a fellow police officer, reaffirming their resolve to clean up corruption. The duo remains vigilant, ready to face new threats.
