After the passing of her husband, Mrs. Sharma lives an impoverished lifestyle near Daryaganj, Delhi, along with her daughter, Razia/Radha, and son, Kishore Kumar. She has managed to get Radha engaged to Inspector Mohan, and Kishore to Asha. Things change suddenly when everyone finds out that Kishore is a petty criminal – resulting in both engagements getting annulled. Hoping to shed his past, Kishore re-locates to Bombay and finds employment with Shewakram for supplying medical supplies. His mother receives news that he is now settled in his new job and both she and Radha re-locate to Bombay. Little do they know that soon she will be compelled to disown Kishore when they find out he was responsible for the death of a young boy by the name of Gopal.
