One day, Mythili finds Madhan riding a bike with a girl at the pillion. On the next day, Mythili gets shocked to see the news that the girl whom she spotted with Madhan the previous day goes missing. Mythili thinks that Madhan is behind all the crime and informs police about Madhan and his whereabouts. Madhan gets arrested.

The story moves to a flashback where Madhan Raj, an innocent guy comes from a village to join engineering. He falls in love with his classmate Vaishnavi (Sindhu Tolani).

But Madhan Raj’s friends inform him that Vaishnavi has an affair with her relative Seenu who also studies in the same class. When Madhan Raj asks about this to Vaishnavi, she gets angry thinking that Madhan Raj does not trust her.
Madhan Raj realizes his mistake and goes to Vaishnavi’s house to apologize but gets shocked to see her on bed with Seenu. He also hears Vaishnavi’s conversation with Seenu that she pretends to love Madhan Raj but would like to marry him, so that she can take advantage of his innocence and sincere love which will help her lead a life the way she wants and Madhan Raj will be like a slave for her throughout her life.
