Rowdran (R. Parthiban) is an upright cop who is fighting not only the scums of the society but also his seniors who are hand-in-glove with the goondas. For this, he takes law into his hands and goes on an unstoppable killing spree wiping out the wanted criminals in police files, one by one in carefully planned operations.

But soon, the film goes from a legitimate thriller to a typical revenge drama without much warning. In a flashback, we are told that our orphan cop had a picture-perfect family which was wiped out by Badri (Milind Soman). And now to bring the don back from a foreign destination and take revenge, Rowdran who is put behind bars turns a goonda and joins Sena (another don) and takes on Badri.
