Charanraj and Saranya are the parents of twins, Vel and Vasudevan (both played by Surya). The couple has lost Vel while traveling in a train. Lakshmi from a rich family in a village brings him up with motherly love and affection. Lakshmi's son (Nasser) and wife (Ambika) get killed by a sugar mill owner and Minister (Kalabhavan Mani) for exposing his corrupt practices. The family has since been in perpetual conflict with the Minister. With the rivalry turning bitter, Vel is out to settle scores with the Minister. Scuffles between them become a daily routine. Vasudevan comes to know by accident that Vel is his twin brother and comes to the village and sends him to the city. As Vel is emotionally attached to the Lakshmi family, Vasu wants him to stay with the family and cement the bonding. To help his brother, Vasu enters the fray to eliminate the arch rival.
