Aradhona (1979)

SPOILER: Rupa is a village girl who lives with her brother Abul. She was married to Ashik, a doctor who died by sinking boat on their wedding night, and she lost her memory and her sense after hearing the news. A few days later Dr. Masud, Ashik's lookalike, comes to the village and Rupa thinks he is Ashik. Masud offers to take her to his professor for treatment. Abul and Rupa go there and stay at a hotel, which Masud visits every day; his wife Parul somehow knows this. Now it is time to explain to Parul about Rupa's condition and to Rupa about her disease.
