Unknown to Dilipkanth, Saravanan and crew manipulate him into situations that match the storyline of the movie they are shooting for and capture Dilipkanth's live reactions. Determined to finish the movie, Saravanan seeks the help of his crew and friends in the cinema industry. Shooting starts with Dilipkanth as hero but is halted midway owing to various tantrums thrown by the new opportunistic hero. However, he finds out that he can't make his film unless Dilipkanth plays the hero. Saravanan does not give up and creates another story. The movie turns Kanniah, now rechristened Dilipkanth, into a star.
Impressed by the script, the producer agrees to the condition. When Saravanan goes to Hyderabad, Kanniah copies Saravanan's script and pitches it a producer, under the condition that he has to play the hero in the film. Kanniah (Prakashraj), who has been looking for a break as an actor for even longer than Saravanan, becomes Saravanan's roommate. Saravanan(Prithviraj) is an assistant director who feels he has written a script that only he, as a director, can do justice to. Jaikumar is awarded the Kirti Chakra posthumously.

They locate the terrorist and Mahadevan recognises the man as the one who killed his wife and daughter. But a civilian informs that the chief of the terrorists is not to be seen among the corpses, and the commandos start a combing operation in the house. After a long operation, the team kills the terrorists, frees the civilian hostages and disarms the missile. The patrolling team intimates the NSG, and Mahadevan and his team immediately join the battle. A military patrolling vehicle hears the gunshot as they approach the house, they are fired upon. Some of them rape a girl in the house and shoot a person who protests. They hijack a house that offers a good vantage point on the shrine and plant the missile there. Meanwhile, a group of terrorists from Afghanistan and Pakistan conspire to hit the Hazratbal Shrine with a missile they think this will create unrest in the region and that the Indian army will be blamed.
She later understands the situation and the sincerity of the commandos and decides not to proceed with the complaint. A human rights activist (Shwetha Menon) learns about this and threatens to file a complaint with the government. Later, during an operation focused on some cottages near the Dal Lake, a commando in the team is killed and an outraged Jaikumar shoots down a captured terrorist who challenges the commandos. The commandos raid a mosque in civilian dress and seize a big collection of arms and explosives. He calls back his buddy Havildar Jaikumar (Jiiva) from his honeymoon because he has information about major activities of the militants he feels Jaikumar is needed for the team.
