Raat Aur Din (1967)

Varuna is seen singing and dancing in a nightclub with a stranger, Dilip; suddenly Partap arrives and confronts her, stating that he is her husband. But she claims that she never married and her name is Peggy, which leads to a tiff between Dilip and Pratap, which Varuna manages to escape. The next morning Pratap confronts her about the night before, but she denies knowing anything and claims she was in the house all night. Dilip arrives to apologize saying he was with Varuna in the club last night. Pratap and Dilip decide to take medical assistance from Dr Dey and Dr Alvares and find that it could be a mental disorder of Varuna having two personalities, and to figure out a solution they should find her past. Pratap tells the doctors how he met Varuna in Shimla and got married and never came across anyone called Peggy, while Dilip just saw her for a few minutes at a party in Shimla a few years back and knows nothing beyond that. Varuna is kept under observation where doctors examine her when she turns into Peggy at night and does not remember anything when she is Varuna during the day. Varuna's condition worsens while Pratap loses his patience and his cool on her; to make it worse, Varuna goes missing from the hospital while Peggy remains a mystery.
