Karthick (Jai) is a jobless youth who leads a jolly life. He falls in love with Janani (Vijayalakshmi). He falls for the moment once he spots her. However, on his father's ('Nizhalgal' Ravi) advice, Karthick goes to Australia for a year to pursue his studies. His father takes a promise from him that during his stay in Australia, Karthick should not communicate with Janani. Meanwhile, Janani's wedding is arranged with a rich industrialist Siva (debutant Rahul). During his return journey from Australia, Karthick meets Siva by chance and they become good friends. Siva tells Karthick to teach a lesson to Janani for cheating him without realising that she is his wife.
