Vikram

Amar, leader of a black ops squad, is summoned by Police Commissioner Jose to track down masked vigilantes who killed Stephen Raj, ACP Prabhanjan, and Karnan's foster father. He begins the investigation by digging into Karnan's life and the contrast between Karnan as an ordinary man and the high level of the earlier victims. The mission sets the tone for a citywide confrontation with a hidden drug network.

Amar learns Karnan s alcohol and prostitution addictions are a cover for a covert operation. He discovers two drug containers are missing and that Sandhanam is hunting for the shipment. The pursuit links Karnan s past to a wider drug syndicate and raises the stakes for the investigation.

The masked vigilantes kill Veerapandian at a theatre, signaling their reach and danger. Bejoy is captured, revealing his ties to the vigilantes and his motive to fight back after a family tragedy. The police tighten focus on the offences and the vigilantes become more dangerous.

Bejoy explains that his family was killed due to his role in leading a drug bust in Trichy, pushing him to join the vigilantes. Amar and his team realize Rudra Prathap has become the next target and move to intercept. They plan to confront the danger at Rudra Prathap s daughter's wedding.

The masked men arrive at the wedding, threaten Rudra Prathap, and attempt to seize him. The leader drags Rudra Prathap away on a bike and escapes amid the commotion. Amar and his team close in, but Karnan remains elusive.

Amar confronts the masked leader and learns Karnan faked his death and is in fact Vikram, the former commander of the black ops squad. Karnan kills Rudra Prathap and escapes, confirming a personal vendetta intertwined with the bigger conspiracy. The revelation deepens the tension between Amar and the fugitive Vikram.

Amar informs Jose that Karnan is Vikram, linking past missions to the present. He discovers that Jose is Sandhanam s mole in the police department. In a bid to cripple the drug syndicate, Amar organises a bomb blast at Sandhanam s bungalow, destroying the drug lab and the syndicate's operation.

Vikram frees Bejoy and his team from prison, claiming that defeating the drug network is the real goal and not personal vengeance. He reveals that Prabhanjan is his biological son and acknowledges his hidden identity. Bejoy joins Vikram, reaffirming the alliance against Sandhanam.

Sandhanam kills Amar s wife Gayathri by beheading, escalating the personal toll of the war. He then orders his men to target Vikram s daughter in law and grandson at Prabhanjan's house. Tina, disguised as Vikram s housekeeper, infiltrates the attackers and sacrifices herself to stop them.

Amar confronts Jose after learning of the mole and the assault, and kills Jose to avenge Gayathri s death and to disrupt Sandhanam s plans. The two factions clash as Vikram s alliance with Amar strengthens against the drug syndicate.

Vikram reaches Chennai Port where the hidden containers are stored and engages Sandhanam s men in a fierce fight. He uses a cannon and an M2 Browning to wipe out attackers, while two of his own agents die. After a brutal fistfight with Sandhanam, Vikram triggers a massive blast that destroys the port and kills Sandhanam.

A week later Adaikalam and Anbu arrive at Sassoon Docks, Mumbai, to meet with Sandhanam s gang and discuss Dilli s involvement in the Trichy ambush. Sandhanam s men reveal Vikram s and Amar s involvement in destroying their drug network. The meeting foreshadows a wider battle between rival factions.

Gayathri s funeral takes place in Ernakulam, marking a turning point as Amar joins Vikram s gang to work toward a drug free society. He commits to the joint cause and builds new ties with Vikram. The alliance signals the start of a broader effort to clean the city.

Anbu informs Rolex that Dilli is hiding somewhere in Uttar Pradesh, triggering a public bounty on Amar, Dilli, and Vikram s team. Rolex arranges the reward and mobilizes new threats across the city. Unknown to others, Vikram attends the bounty meeting and walks away, hinting at his plans to outlive the hunt.
