She is married off to software professional (Ravi Varma) who plans to go to USA. The greedy in-laws burn her alive for more dowry. Devastated by this he takes the law into his own hands and starts to kill men for harassing women. A police officer Meenakshi Iyer (Suhasini) convinces him to surrender to the law. Before surrendering, he has killed over 49 misogynists. Finally in jail, he kills his sister's friend's murderer like a tiger and in the climax, the main villain ministers. His dialogues in the court are remarkable. The court drama forms the rest of the story.
