When an airplane brings 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 Hussain). Manju (Madhubala), daughter of 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.
