From Janwar (1965). I want to see this movie. IMDB says:
Mr. Srivastava lives a very wealthy lifestyle with his wife, and two sons, Mahendra and Sunder. He plans to get both his sons married to women from equally wealthy backgrounds. This does not happen, as Mahendra falls in love with Seema, who is poor and lives with her stepmother. This creates considerable acrimony in the family, and Seema is not accepted as a daughter-in-law. Unable to find a solution, Mahendra takes to alcohol and falls in the bewitching clutches of a beautiful courtesan by the name of Bahaar.
While vacationing in Srinagar, Sunder meets with Sapna, who also comes from a poor family, falls in love with her and wants to marry her. She, too, falls in love with him. After the vacation, the two then part company. The next time Sapna sees Sunder in the company of a pregnant woman, and overhears that Sunder is soon to be a father. Did Sunder decide to obey his father's instructions after all? If so, what is to become of Sapna?
The Ottawa Public Libary has a bunch of Bollywood titles, but they don't have this one.
