Thiyagu (Vikram), a Medical College Student, leads a gang of four to abduct corrupt politicians and bureaucrats who use the loophole in the law to enjoy their prison term in hospitals or guest houses. Deiva (Anitha), a schoolgirl and daughter of Sandana Pandian (Nassar), a police officer on the trail of the mysterious gang, has a crush on Thiyagu. She is not aware of his real identity. The reason for Thiyagu to take up illegal activities is out of frustration. His collegemate Kavitha (Jayaseal) commits suicide when she doesn't get any support from him in her effort to expose a drug sale racket in the medical college. This shocked him and spurred him into taking law into his own hands. Nabbed by Sandana pandian and hauled before the special court, Thiyagu reveals the crimes committed by those he had kidnapped. He offers to free them if they are sentenced to life imprisonment. When the judges refuse, the public storm the court. In the melee, Sandana Pandian lets the gang members go scot free along with his daughter.
