Medical student and playboy Selvam (Ganesan) falls for the wiles of Vasanthi (Priyadarshini) who only appears to covet his ancestral wealth. Later Selvam meets the schoolteacher Shanta (Saroja Devi) who is forced by her parents to marry him. However, she refuses to live with her husband because of his earlier affair. When Selvam is accused of murdering his former girlfriend, the crisis reconciles the couple. The playboy song Paravaigal palavidham (sung by T.M. Soundararajan) was a hit. Prasad produced the Hindi version made by T. Prakash Rao as Sasural (1961) starring Rajendra Kumar.
