Nai Roshni.

A neglected wife, Indira, schemes to win back her philandering bank manager husband, Bihari. She uses an unwitting musician, Madan, as a pawn, making him fall for her until her husband's jealousy is ignited. Once Bihari returns, Madan is quickly married off to the daughter of a poor clerk, Mohan, to neatly tie up the loose ends.
