Knowing his evil intention, the paternal uncle keeps his son's whereabouts a secret which is known only to his loyal personal secretary Shanthi (Bharathi). One night after a bitter argument over the properties, Jagatheesh kills his uncle and abducts his secretary Shanthi to find out about his young son Babu.

Meanwhile, Raju (Ravichandran, son of a rich man Chinna Durai (Major Sundararajan) is thrown out of his house by his stepmother Shantha Lakshmi (S. Varalakshmi) and lands in the city as a taxi driver. The secretary Shanthi gets abducted in his taxi, the news is in the newspapers and the police start looking for the taxi. Raju then goes after Jagathesh and finds Shanthi locked up in a cell on a remote island. Jagatheesh finds out the whereabouts of the boy but is unable to identify him, so he abducts a busload of boys from that school and forces Shanthi to identify the boy so that he could kill him. Raju, with help of a small-time magician Chithambaram (Nagesh), rescues Shanthi and the boys after a series of fights with the gangsters. Raju and Shanthi get married.
