Sethupathi IPS

Sethupathi (Vijayakanth) catches terrorist Sivasubramaniam in a hospital and coaxes him to reveal information that their gang is planning a terrorist strike on the Prime minister of India during his meeting with Chief Ministers of various states in Chennai. After divulging this information (owing to the kindness and pity shown by Sethupathi), the terrorist commits suicide with Sethupathi's gun. Using the information Sethupathi is able to save the day and the Prime minister. Sivasubramaniam's death leads to his brother Sivaprakasham (Raj Mohan) arriving in India. Sivaprakasham is also the leader of this terrorist gang which plans to wipe out Sethupathi's family. The rest of the movie is about Sethupathi's plan of action.
