The second wife of kind-heartedand generous Amirchand Bhargav is Durgadevi Bhargav (Nadira) who is exactly the opposite of her late husband. She rules over her household alongwith her brother Makhanlal (Madan Puri) with an iron hand and also over her step-daughter Shanti (Vidya Sinha) who she treats worse than her servants. Due to her brutality there is always a dearth of servants in her household and hence most of the work must be done by Shanti. Her other daughter is Roopa (Moushumi Chatterjee) is bad-tempered and spoiled. When a former employee of Amirchand Ratanlal (Shreeram Lagoo) approaches Durgadevi for marrying his two sons to her two daughters she humiliates him and turns him away. Unperturbed by this he asks the assistance of his two sons Ram (Sanjeev Kumar) and Laxman (Shashi Kapoor) so that the marriages can take place and at the same time Durgadevi and Makhanlal be taught a lesson. Both the sons readily agree to do this and Ram goes to Durgadevi household as a servant to woo Shanti; while Laxman poses as a wealthy playboy to woo Roopa. But Makhanlal and his wife Jwala (Shashikala) want Roopa to marry their jailbird son Chander (Ranjeet) and will not stop at anything including abducting Durgadevi herself to pave their way to wealth
