A looming gangster after witnessing a bone chilling event, stands up against his father’s prejudice.

An easy-going taxi driver, Shiva (Karan) gives out advice on hygiene and the need to be ‘professional’ to an idli vendor on street, thus establishing himself as someone with a humanitarian side, in the very first scene. Further, his conversation with Gnanasambandam (who plays himself) in a car and the way he talks to his over-concerned mother over phone (Kovai Sarala’s voice) brings him closer to the audience. However, within no time, things go haywire when the story actually kicks off.
Nila (Neha) is being chased by a prominent drug dealer (Naren) in the town, and Shiva comes to her rescue and offers a lift. He tries to contact people who are close to her to ensure safety. Little does he know that he is inviting trouble, as things start going beyond his control. What follows is an unexpected series of incidents.

James Vasanthan (Madhavan) and his three friends Ganeshan (Charle), Charles (Vaiyapuri), and Mohan (Venu Madhav), have a music troupe that sings at weddings. They are tenants of Subramani (Manivannan) whose daughter Lakshmi (Sneha) shares a good rapport with the youths, helping them in their time of need. Her encouragement puts a new zeal in James, who soon gains recognition as a singer. Not that this brings any change in the group’s lifestyle, for J. Suresh still shows them as strugglers. James finally proposes to Lakshmi who rejects him, as she has her past to reckon with. She is a divorcee, her husband having abandoned her soon after marriage for his girlfriend. When Lakshmi’s friend and neighbour Seetha (Aswini) puts some sense into her, she decides to make amends. Incidentally, Seetha had been hovering in the background doing almost nothing until she gets this scene to justify her presence in the film. But misunderstandings pile up between the lovers – the situations are all forced here – until J. Suresh leads the story to a desired happy ending.

The film opens with Pavalakkodi (Nayanthara) in the hospital and her father Vairakannu (Thambi Ramaiah) weeping for her misfortune. Later, the scene cuts to their futures.

They lead a happy life. Nearby in an apartment, three thieves enter a house and rob all the jewels from the lady, harass and kill her. To investigate this case a Police officer (Harish Uthaman) arrives at the site and finds no clue about the men and finds a Rajasthani blanket in the house. Upon asking, the house owner and maids say nothing, and therefore the case leads to nothing.

Despite Balu’s request to execute him as a martyr by shooting, the court orders that he be hanged within a month’s time by a professional executioner or hangman. He is escorted to a high security prison complex in Chennai by Macaulay (Shaam), an honest, law abiding police officer who is given the charge of monitoring him until his execution. The prison provides freedom to all prisoners, including Balu, to do whatever they want, as long as they do not cause unrest. Balu is instantly admired by the inmates for his patriotism and philosophy as well as his empathy with the inmates. They view him as a spokesperson to the prison officials on behalf of them.
