The film won critical acclaim for its story and Nargis' performance as Varuna.

Pratap tells that once he was going to Shimla, when his car broke down and was forced to stay at Varuna's house, during which both fell in love.

Once at a picnic, a boulder slides down a cliff, which triggers some childhood memories of Varuna and she screams.

The next day, Pratap leaves town for an emergency but after coming back, finds someone is heavily drinking alcohol, but couldn't reach a conclusion.

The doctors would follow and she displays both Varuna and Peggy simultaneously, but then completely loses her mind.

Once she leaves the party, Varuna's mother finds out and says she is not her daughter anymore and is angry, but slides down a cliff and dies.

Nargis had retired from films after Mother India (1957) to marry her co-star Sunil Dutt the following year and start a family.

Her brother Jaffer Hussain lured her back to do this film, as he was the producer who was going through a difficult time, and she decided to help him, with the support of her husband.
