She takes him to her home, upon which he reveals his name as Mohan (Sunil Dutt), and as the son of a rich landlord (Bipin Gupta). Mohan runs a hotel business in the city much against the will of his father.
A dejected Mohan finds solace in Kamla, and they fall in love with each other. But when he gets to know that Kamla is a stage dancer, he calls her as a prostitute.

In order to rescue Mohan, Kamla takes up the blame of the murder. Padma, a prime witness of the murder, undergoes an operation and regains her eyesight. She reveals the truth that Shankar was the real murderer. Shankar kills himself with a gun. Mohan's mother (Achla Sachdev) and sister (Ragini) become happy and accept Kamla.
