Subramaniyam Siva is in jail, awaiting the death sentence for killing corrupt and evil members of the police force who had killed his father SI Ganapathy and sister. SP "Nethiadi" Nandakumar is an honest, fearless police officer who has been given the mission to flush out the terrorist outfit behind the Coimbatore blasts. He decides to employ unconventional methods to fulfill his mission. He Siva to assist him, renaming him Paramasivan, changing his appearance (cutting his Jaṭā hair), and giving him a single-point agenda: trace out and erase the people responsible for the Coimbatore blasts. Unaware to Paramasivan, Nandakumar intends to kill him after the mission is completed.

The fly in the ointment is CBI officer Nair, who is out to trace Paramasivan and stop his unlawful activities. His assistant SI Agniputran provides lighter moments. How Paramasivan finishes the villains and his job forms the rest of the story. Paramasivan learns of Nandakumar's plan to kill him after the mission during the last few scenes, where Nair intervenes.

After the success of Chandramukhi (2005), director P. Vasu wanted to direct an action film, and cast Ajith Kumar as the lead actor.
