Burma-based widow, Parvati, along with two sons, Prem and Rajesh, re-locates to Bombay to live with her late husband's friend and widower, Sewakram, and his two daughters, Shanti and Durga. He returns some cash and jewelery to her that was entrusted to him, and she re-locates to live in a big bungalow. Shortly thereafter, Prem and Rajesh get married to Shanti and Durga respectively.
