Sathya and Vasanth are best friends since childhood. Kumaraswamy is working under Sathya's mother and he wants his daughter Pooja to marry Sathya so that he would be wealthy for the rest of his life. For this he makes many tricks and pranks to make them walk together alone, to go for a ride and many more. On Vasanth's birthday Sathya goes to wish him but he denies his wish and says his birthday means nothing to him anymore. Simultaneously Sathya's mother decides that her son is to marry Pooja and the engagement day arrives. Without informing her, when she enters the house as all the other guests did, Kumaraswamy insists that she wear the engagement saree. Knowing the situation she leaves the place crying and Sathya follows her. In the middle of the street he shouts at her and asks the reason why she can't marry him. She immediately shows her Mangala sutra (wedding thread) which she has hidden from everyone and reveals that she is already married.

The flashback begins with Nivetha and Pooja being best friends from school and on the first day of college Nivetha meets Vasanth and falls in love. Unaware of this, Pooja and Vasanth love each other. When Pooja discovers her friend's love for Vasanth, she decides to sacrifice her love. On Vasanth's birthday she denied her love for him and quickly he forcefully married her. Seeing this, Nivetha kills herself before their eyes. Pooja separates from Vasanth thinking that he was the reason for her friend's death.

After knowing this Sathya goes on to have a fight with Vasanth. But after knowing the truth, Sathya decides to sacrifice his love for Pooja and decides to unite Vasanth and Pooja. On a cultural day when Sathya, Vasanth and Pooja give a combined performance, the opposite gang led by Kumaraswamy plots against Vasanth and stabs him. The blame is then put on Sathya who is jailed. When Pooja sees her husband get hurt, she forgets everything and starts to cry for him. When Vasanth regains consciousness, he and Pooja finally are united.
