Guru (Prabhu Deva) is a graduate but cannot find a job because employers are looking experience. He and his pickpocket and bike thief friend Indhu (Rambha) live along with an auto mechanic (Manivannan) and his wife. The couple is a Muslim and the lady wears a purdah and it is shown that whoever lifts her purdah and sees her face faints immediately. Manivannan himself has seen his wife's face only during their first night. This provides comic relief.
Anupam Kher is a rich businessman but his business is about to topple when he invites his nephew Santhosh (Abbas) from the US to save it from loss. Priya (Simran) is his daughter and she expects to marry Santhosh when he arrives. Meanwhile Guru steals a car from a businessman who refused to employ him and when the goondas chase, he and Indhu enter into the airport and in a series of comic events, Guru ends up in Priya's house as Santhosh and Santhosh who tries to save Indhu lands up with her in Mizoram.
Anupam Kher introduces Guru (now Santhosh) as the new managing director of the company to his employees. He also encourages Santhosh to take up the new assignment. Guru, who is a talented youth works hard and brings the company back to business meanwhile the real Santhosh struggles with Indhu to get back home. When Santhosh gets back to Chennai, he collects his bags and passport from the airport.
By now he has fallen in love with Indhu and Priya has fallen in love with Guru. Indhu and Guru meet up and they find out about Guru acting as Santhosh and real Santhosh is with Indhu. When Santhosh finds out that Guru has actually taken the company to greater heights than he would have, he accepts Guru as his friend and doesn't reveal his true identity to his Uncle's family. In the end all confusions are cleared and the lovers unite.
