 Meena lives with her retired and widowed dad in picturesque Nainital. She has a sister, Kamla, married to a well-known Barrister, Ashok, and two children, Pappu and Dolly. When Kamla comes for a visit, she finds out that Meena is in love with Rajendra, a painter and singer, who she approves of him, and would like to get them married. Before that could happen she has an accident and passes away, leaving the care of her children to Meena. Subsequently, their father arranges Meena s marriage with Ashok, fearing ill-treatment by another woman as the step-mother. Meena marries Ashok and goes to live in his palatial house in Bombay. After a year when they return to Nainital, a visibly upset Rajendra gets in touch with Meena and they rekindle their romance. When Meena gets back to Bombay, Rajendra follows her and they continue to meet in secret. Things gets complicated when Meena finds out that Rajendra is married to a woman named Leela, who also wants to blackmail her in order to keep her mouth shut. Angry at this betrayal at the hands of her lover, Meena has two ways out - continue to pay Leela for the rest of her life - or kill herself.
