Sathya (Sadhan) is a fearful college student from a middle-class family. His relative Pooja (Jayashree) and his collegemate Nandhini (Aishwarya Rajesh), the daughter of Vallal Perumal (Srinivasan), are in love with Sathya, but they could not reveal their love to him. Vallal Perumal is an influential and respected man who helps the poor the day, but the night, under a new getup, Vallal Perumal becomes a pervert, and he has raped many women without getting caught.
The police inspector Thamizhselvan (Sriman), who gets transferred to his area, starts to investigate these crimes. One day, Sathya is mistaken to have killed Pandian, the brother of the gangster Aadhi (Kadhal Dhandapani), and Thamizhselvan arrests the innocent Sathya. A vengeful Aadhi then murders Sathya's mother and Sathya's sister. Thereafter, a fearless Sathya joins Vallal Perumal. Aadhi wants to win the local election, so he asks Vallal Perumal for his support, but Vallal Perumal declines. In the meantime, Thamizhselvan finds out that the rapist is none other than Vallal Perumal. One night, Thamizhselvan, Vallal Perumal, Aadhi and Sathya had a violent fight. During the fight, Sathya stabs Aadhi to death while Vallal Perumal is killed by one of his victims. The film ends with Sathya being released from jail and returning to his lover Nandhini.
