This film is about families who are neighbours and are strongly connected with each other. Gurcharan Babu (Nasir Hussain) who is very poor, is in deep debt. He has taken a loan from his neighbour Nabin Roy (Badri Prasad). Nabin Roy's son, Shekhar (Ashok Kumar) and Gurcharan's niece Lalita (Meena Kumari) love each other, but secretly. Charu, Lalita's childhood friend, is another neighbour. One day, Girin Babu (Asit Baran) who is Charu's uncle, comes to visit their house. Girin Babu then starts liking Lalita. He visits their house often and learns that Gurcharan Babu is in deep debt and then he decides to help them out. He gives a loan to Gurcharan Babu without charging him any interest. After some days Gurcharan Babu proposes Lalita's hand in marriage to Girin Babu. Almost everything is fixed, however, Lalita and Shekhar are hurt. On the other hand, Nabin Roy was hoping that Gurcharan Babu would be unable to pay his debt and then we would be able to confiscate their ancestral house, as that was mortgagaed against the loan. When Gurcharan Babu repays the loan, Nabin Roy loses his temper and there is a big fight between him and Gurcharan Babu. This divides the two families. Will this misunderstanding be resolved? Will Shekher and Lalita be reunited again. Watch this film based on subtle emotions, directed by none other than Bimal Roy.
