Balakrishnan "Balu" is a die hard fan of singer Sangeetha. By chance Sangeetha visits Balakrishnan's village for a vacation. When he tries to meet her, he is continuously ragged and insulted by her and her assistants. One day when Sangeetha hears him sing near a beach, she realises his talent and also learns about his struggles. They become good friends and Sangeetha wishes to stay in the village for longer. However her father comes and immediately takes her back to Chennai for her singing events and she leaves without informing Balakrishnan. Balakrishnan heartbroken goes to Chennai in search of her and finally when he reaches her home, he gets insulted. On that day he decides to take revenge on her by becoming a popular singer just like her. He is helped by a policeman who suggests that he learn singing from a man in jail. So Balu goes to the jail where he finds the man to be his father. But he does not reveal the truth in fear of being unable to learn from his father.

After learning proper music he becomes a good singer. He meets Sangeetha while in jail where she comes to sing in a function. He sings in front of her and she becomes very happy while he remains angry. She later gives him the chance to begin his career as a singer at her own studio and he becomes famous. Now she meets singer Balu at his house but he insults her the same way she did at her house. She then tells all the truth that she insulted him to protect him from her money minded father. He then acts as if he believed her and embraces her while planning his revenge. They get married and the next day Balu leaves her at her home. When enquired about why he behaves so, he says he did it all to take revenge on her and her father. It is revealed that Sangeetha's father killed Balu's sister and his innocent father was framed for the same and sent to jail. Balu challenges Sangeetha for a music competition with the condition that the loser should never sing again. Her father decides to kill Balu on the day of the competition. All the efforts to prevent this go in vain and the competition begins. Both of them sing fabulously and in the end, Sangeetha gets injured while protecting Balu and her father is shot dead by the police. He gives a last statement that Balu's father is innocent and he is the killer. Balu's father is released from the jail. Balu and Sangeetha finally unite.
