Prabhu (Dhanush) is a happy-go-lucky middle-class family guy who spends time playing carrom. He and his father (Murali (Malayalam actor)) fall into minor misunderstandings, and he indulges in a romance with Hema (Divya Spandana). When Prabhu is caught in stealing a pittance from his father for booze with his friends, he questions his father's responsibility towards his upbringing. His father gives Prabhu some of his savings and tells him to do something with his life. Prabhu purchases a Bajaj Pulsar bike and finds a job. The bike saves his life from a freak incident and later gets lost. When his family members ask him about his bike, he tells them that he has given it for dealer service.
