Kesavan (P. Vasu) is a famous Carnatic singer who performs concerts. He lives with his family, consisting of his wife and son. Seenu (Karthik) is his younger brother who leads a joyful life.
Seenu falls in love with his relative Malavika. When the family members come to know about Kesavan's habit of consuming alcohol, they advise him to stop it as it will bring down the fame what he has earned so far.
Kesavan develops a habit of consuming alcohol, which is only known to his wife. Seenu tries hard to stop Kesavan from drinking, but all his efforts go in vain. When Kesavan goes to a concert after drinking and stumbles on stage, Seenu starts singing in place of Kesavan in the concert.
Seenu's singing ability is great, and he is appreciated by everyone. However, Kesavan develops an ego within him, thinking that Seenu will overpower him. This makes Kesavan behave rude towards his family members, especially Seenu.
The film ends with the entire family getting back to happy mode on the event of their sister's wedding. Kesavan is also recovered and decides to go on a pilgrimage trip before his sister's wedding so that he could return pure.
