Raat Aur Din

Once, during a late night a woman named Varuna goes to a club and dances with an unknown club man named Dilip. He mentions meeting Varuna in Shimla before, but she denies ever being in S. Meanwhile, her husband Pratap follows her. Upon confronting her, she says her name is Peggy and denies ever being married to him, and soon leaves. The next morning, back at the house Pratap again confronts Varuna about the previous night, but she denies ever leaving the house; meanwhile, Dilip arrives and confesses to being in the club with Varuna.

At a clinic, the doctors say that it might be MPD, but are unsure until they know about her past. 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. But once the car was fixed, Pratap left as he was going to Simla for marriage approval, but doesn't accept and returns to Varuna and get married, much to the disapproval of Pratap's mother. After this, Varuna frequently gets headaches and at night would dance to loud music. Once at a picnic, a boulder slides down a cliff, which triggers some childhood memories of Varuna and she screams. Her mother-in-law arranges a witch doctor, believing Varuna is under Voodoo, but is unsuccessful. Things become a bit better on holidays, but at a party at home, Varuna drinks alcohol. 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. Then comes the night when Varuna goes out in the club and dances with Dilip.

In present, a few days later the doctors tell Varuna is sick and is admitted to a mental institute to have her treatment, but her MPD keeps getting out of control and she would leave the institute. The doctors would follow and she displays both Varuna and Peggy simultaneously, but then completely loses her mind. Later, she gets shock treatment, but it's unsuccessful. She would then walk on the streets at night and would sing. She comes to a random house in the rain and gets unconscious. The woman in the house says that Varuna is pregnant, but it is Peggy on the mind and denies being married and asks for an abortion, but the woman doesn't know how. After some time, when Varuna wakes up, she is Varuna and the woman again tells her about being pregnant. At this time, Varuna realizes that whatever she was denying was all true and knows she has MPD. She returns home, but her mother-in-law doesn't allow, claiming she is unfaithful. Varuna then meets a minor road accident and is hospitalized. Pratap and Varuna's father come, but she is in shock and couldn't figure out anything. Something triggers her mind when a nurse drops a tray. The doctors ask Varuna's father to tell about Varuna's past. In the past, Varuna's father was a heavy gambler and would abuse his wife. His wife leaves for Shimla with Varuna.

At Shimla it all comes to Varuna and she reveals what happened in Simla. After leaving, Varuna's mother would keep Varuna isolated, but Varuna secretly befriends a neighbor girl named Peggy. Peggy is a very sweet girl who dances with loud music, which makes Varuna want to dance also. Her mother would get harsh if she found Varuna talking to Peggy. Once grown, Varuna leaves the house and goes a Christmas party secretly. There is also Dilip sitting and watching. 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. Varuna blames herself for her mother death. The doctor informs that this trauma caused Varuna to hate herself and make a new personality named Peggy because she yearned for her lifestyle, which caused her MPD in the first place. In the end, the doctors reveal her mother died of heart failure, by which she lost balance and died falling off the cliff, and Varuna is cured after hearing and regaining self-confidence in her Varuna personality.
