The story begins with Sarathy (Sundar C.), a tough but honest cop. Given his straightforward nature, he is the thorn in the flesh for many antisocial elements and politicians. Due to this, he keeps getting transferred from time to time but has no qualms about it, since he is happily married to Ganga (Ramya Raj). However, Sarathy's life takes a turn when he arrests a corrupt MLA J.P. (G. M. Kumar) and his men, which leads J.P. to quit the field. J.P. vows revenge, so he kills Ganga and her two children. He also frames Sarathy in a case. Ganga escapes, and Sarathy admits her in a hospital in serious condition. This enrages Sarathy so much that he decides to take a different route. He becomes Saami, and with the help of a top hot actress Ruchi Devi (Namitha), he obtains a political ticket and successfully becomes an MLA. His wife gives birth to a child and dies in the hospital. From then on, he begins his corrupt acts in such a way that the entire society begins to loathe the police force. In no time, the police are vexed and decide to go on an indefinite strike. The entire system comes to a halt and things begin to get messy. Saami then strikes hard at J.P., and what happens from there forms the rest of the story.
