Bewafai (1985)

This evocative romantic drama centres around a woman named Asha (Tina Munim), who has been in love with a man named Ashok Nath (Rajesh Khanna) since childhood. But somehow she was never able to convey her feelings for him throughout her childhood and college days.

Now Ashok works as her dad's employee. She becomes very possessive about him to the point where she cannot stand the thought of another woman trying to woo him. The possessiveness becomes so strong that Asha beats up a woman named Vinny (Meenakshi Seshadri) over Ashok.

She tries her best to ensure that she keeps herself aware of Ashok's whereabouts. Renu (Padmini Kolhapure) falls in love with Ashok and when this fact is revealed to Asha she becomes heartbroken. She comes to know that Ashok has been taking care of Renu for a long time. Asha decides to meet Renu to teach her a lesson but when she finds that Renu is a mental patient and Ashok has been nursing her, she changes her heart and begins to assist Ashok in serving the mentally imbalanced Renu.

Their lives take an unexpected turn when an unknown person shoots Ashok and leaves him mortally wounded. The rest of this relationship drama depicts whether Asha gets a chance to convey her feelings for Ashok, how Renu became a mental patient, the nature of the relationship between Renu and Ashok, and how all their futures pan out.
