Vishnu is a mama's boy, dependent on his widowed mother for everything. He falls in love with Keerthi the second he lays eyes on her. But what happens when his world is shaken apart? Can he cope and keep up with his love?

A united family of two brothers and a sister along with their parents move to a town. Elder brother (Suryam - Ram Mohan) finds easy way to get rich and marries the daughter of a rich politician and abandons his family. After their father expires, tragedy hits the family. The younger brother Vasu (Chandra Mohan) sticks with the family to take care of his mother (Anjali Devi) and sister (Vijaya Nirmala).

Mani Ratnam's next with Vijay Sethupathi.
