Sathyamoorthy alias Sakthi (Vishnu Vishal) is a laid-back constable in the Silukkuvarupatti police station who takes life too easy. Bhaskar (Karunakaran) is a new constable who joins for the job of constable in the same station and is appointed by Sub-Inspector Muthaiya (Livingston) to assist Sakthi. Muthaiya keeps praising Sakthi nonstop due to the takes woven by Sakthi to score good points with him.
Cycle Shankar (P. Ravi Shankar) is a dreaded rowdy and don in Chennai. He is chased by Commissioner Panneerselvam (Aadukalam Naren) after he murders a police officer in public as the officer threatened to finish off Shankar. This starts a cat-and-mouse chase between the two.
Rajeshwari alias Raji (Regina Cassandra) is Sakthi’s “love at first sight”, which she does not reciprocate as he unknowingly insults her. Gradually, however, she warms up to him.
