After Partition, Dhaniram (Balraj Sahni) and his family moves to Dehradoon. He has 3 sons: Pran (Rehman), Kundan (Pradeep Kumar) and Madan (Jawahar Kaul). Dhaniram runs a chemist shop with honesty. Kundan and Pran help him with work. When he refuses to co-operate with profiteers, Dhaniram is stabbed and disabled. Now Pran runs the shop while Kundan moves on to work as a stone contractor. Instigated by his wife (Shashikala), Pran resorts to illegal business to make more money. Family discords create the batwara and house is separated into 2 sections separated by a brick wall. Shortly thereafter, Pran is arrested by the authorities and has to pay 2500 Rs fine or risk jail. Kundan who is in the hospital due to a mining accident, runs back to home, pawns family jewels and pays the fine, while Pran thinks his friend has helped him. Pran's son falls from terrace and requires medicine. No one in the market is willing to give him any, but Kundan brings it and Pran comes to know of all sacrifices made by Kundan. Pran is not allowed to enter home, but his mother (Leela Chitnis) tries to help him thru a hole in the wall and her neck gets stuck. To rescue her, the wall has to be broken down and the family reunites.
