Hoping to impress a wealthy woman named Nita, unemployed and impoverished Bombay-based engineer, Dinesh, is instead embarrassed but redeems himself by getting hired by her father, Hiralal, for a project in Poona. En-route by a state transport bus, his baggage gets switched with a female passenger's. The bag, which is dramatically dropped, contains Rs.1 Lakh and Dinesh gets arrested and is interrogated extensively by the police, who believe he is concealing the rest of the Rs.4 Lakhs as well as who his partners were. Nita attempts to seek bail but before she can, she finds out that Dinesh has not only escaped from prison with the help of an inmate, Mangal Singh, but has subsequently killed himself.
