When her second son marries, his new wife's younger sister Lakshmi comes to stay with the family. Lakshmi's carefree and easy going attitude endears her to the family but puts her at odds with Rajeshwari. Raja, the family's third son and Lakshmi also fall in love. One of Lakshmi's pranks pushes Rajeshwari to her limit and creates fissures in the family. A crisis eventually sets things in motion to solve all the problems.
