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 too reciprocate his love and affection. The eldest of the three, Muthu (Vijayakanth), is a cook in a small hotel. When Vellachamy learns that Muthu is in love with his childhood playmate Gowri (Meena (actress)), he goes to the city to his friend (Rajeev (Tamil actor)) with the marriage proposal, only to be insulted. Circumstances bring Muthu to the city, to Gowri's palatial bungalow where he works as a cook. Gowri is arrogant and rude until she realizes that Muthu is her childhood pal. She does all the wooing and persuades her father to get her married to Muthu.
