Sathyamurthy (Vimal) is the son of a schoolteacher DK (Jayaprakash) in Kumbakonam. Sathya is a happy-go-lucky youngster who yearns to do business. To achieve his ‘mission’, he borrows money from all quarters and is almost drowned in debts. Even as his father advises him to start leading life in a right manner, enters Selvi (Sanusha), a student. Sathya gets acquainted to Selvi, and his life takes a turn. Meanwhile, Selvi is in trouble because her uncle Pandiyan (Sarvajit), a rowdy, wants her to marry him. This proposal was ignored by Selvi, and she hated Pandiyan because he killed her father (Santhana Bharathi). One day while goofing around with Sathya, Selvi loses the necklace Pandiyan had given her. Sathya and Selvi escape to Chennai, but Pandiyan and a corrupt inspector come and trouble them. Sathya switches on the police’s cordless phone, through which an Assistant Commissioner of Police (Sampath Raj) comes to know about Pandiyan and arrests him. The film ends with Sathya opening a cable TV station and becoming successful.
