In Chennai, men and women are mysteriously killed, and the police cannot find a single clue to catch the serial killer. Later, the police cast suspicion on Nandakumar (Mohan), an innocent and single man who runs a resort on the coastal road. They believe that he is a dangerous sexual predator. The police department gives Police Inspector Vandana (Shubha Poonja) the mission of finding enough evidence to convict Nandakumar. Vandana poses as a TV serial dialogue writer and asks Nandakumar for a room in the resort. Nandakumar has no rooms but is under pressure to keep her in his own room in order to gain money and repay his loans.vVandana tries to seduce Nandakumar on multiple occasions by wearing sexy dresses and exposing her body, but she fails every time. Vandana finally realises that Nandakumar is an innocent man who has nothing do with that case, and she falls in love with him. Thereafter, Vandhana finds the culprit: the local church father (R. N. R. Manohar) who lives in a church near the resort of Nandakumar. The church father finds her in his room. He manages to tie her up, and he then confesses the murders. He tells her that he is not a real church father and he killed the victims for having an extramarital affair or premarital sex. In the meantime, Nandakumar is chased by the police, and he enters the church to hide from them. The police then frees Vandana, and she reveals that the fake church father is the killer; thus, the church father is arrested. Nandakumar and Vandana live happily ever after.
