Classic Bollywood drama. Usha Sinha (Madhubala) is part of a wealthy family. She lives with her widowed dad, a retired Colonel. During her birthday party at her grandmother's home in Lucknow, she encounters a flirt, but avoids him, only to run into him again in a taxi, and then in her very own house in Bombay. She finds out that the man's name is Suresh (Ashok Kumar) and he has been hired by her dad as a manager. Usha and Suresh soon appear to fall in love, but what the Sinhas don't know is that Suresh does not love Usha at all - his true motive is to win the family's trust so that he can rob them of their cash and valuables.
