Vellaichaamy (Vijayakanth) thinks the world of his three brothers, even giving up marriage when he learns that the woman he loves plans to send them to a hostel after the wedding. The brothers live with their grandmother (S. N. Lakshmi). Vellaichamy works hard to raise them, and they reciprocate his love and affection too. The eldest of the three, Muthu (Vijayakanth, in a double role), is a cook in a small hotel. When Vellachamy learns that Muthu is in love with Gowri (Meena), he goes to the city to his friend (Rajeev) with the marriage proposal, only to be insulted. Circumstances bring Muthu to the city, where he works as a cook in Gowri's palatial bungalow. Gowri, initially rude towards him, changes her attitude when she learns Muthu had been her childhood playmate, who she had been very close to. Noticing his humble nature, she falls in love with him. They get married.
