When an airplane brings handsome ex dacoit Rangooni (Pradeep Kumar) from Singapore to Bombay. Inspector Mehra (Raj Mehra) looks upon Rangooni's return with well-founded suspicion. His arrival in Bombay disturbs the activities of a gang of jewel-theft specialists, led by man-about-town-Ramesh (Anwar). Rangooni foils the activities of the gang by forestalling the gangster. Manju (Madhubala), daughter of Rai Bahadur Sunderdas, who has encountered Rangooni many times, is excited by the prospect of getting the dacoit arrested and hopes to get a lot of publicity by so doing.
Ramesh, constantly thwarted by Rangooni, lays a trap for his opponent but in the last smashing chase scene is unmasked for what he is.
But who is Rangooni? What is the motive behind his seemingly incongruous actions?
You are just going to find out!
