Harish Khanna (Ashok Kumar) lives in a happy household consisting of his wife Maya (Nirupa Roy) and his large family of seven daughters and one son. Also staying with them is his widowed sister (Lalita Pawar), and her son Jaggu (Mehmood). Harish spends four days of the week away from his family for work. Harish and Maya soon have a ninth child much to Maya's consternation, as her older daughter, Kamla (Bharati Malvankar) who is married to Gopal is also expecting a child. The fact that Kamla is pregnant is a cause of anxiety, as according to Gopal's parents, the couple have not been together since the wedding and her pregnancy is considered as a sign of her disreputable character. Gopal is not there to give an explanation and his parents decide to send Harish's older daughter back home. Harish finds out that two of his daughters, Kiran (Rajshree) and Kamini (Indrani Mukherjee) are in love with Mohan (Manoj Kumar), the son of the College principal, and Ravindra (Soodesh Kumar) respectively, and that Jaggu is in love with Rekha (Shobha Khote). Harish decides to get the three pairs married.However, it is disclosed that Harish has been leading a double life. His second wife is dead and the son from his second wife has come to inform him. Harish explains the situation; his second wife is none other than Maya's younger sister, Radha (Pushpavalli), whom Maya had thought was dead. When Maya's father (Gajanan Jagirdar) had approached Harish to marry his daughter, Harish had assumed it was Radha, as the two were in love with each other. When Radha finds out that Maya too loves Harish, she forces him to marry Maya. Harish and Maya then leave their hometown Meerut, where Harish was helping his father-in-law in his car mechanic business, to go for a job to Rangoon. The time period is WW II, and during a bomb raid, it is assumed that Maya is dead. Somehow Harish gets back to India. There he stays with Radha and her father who is ill. Radha's father has Radha and Harish marry. B
