Custom Officer Verma red-handily catches Jagmohan Lal, alias Jugran, smuggling priceless diamonds through India's airport. Jugran kills Verma before Verma can arrest Jugran; Jugran goes on to murder his twin brother Manmohan Lal and Dr. Ashok Soni. Verma's son Ramesh and Ashok's daughter Seema are sent to an orphanage, where they befriend each other. They are separated when Seema is adopted by a kind-hearted couple while Ramesh runs away and is adopted by expert robber Girdharilal, who teaches him every robber's tricks. Years later Ramesh is an expert safe-breaker--much better at it than Girdharilal. Ramesh changes his name to Romeo, reunites with Seema, and together they work for Jugran, who now has two identities: well-respected Manmohan Lal, known to everyone; and gangster Jugran, known only to his men. Seema and Romeo must wake up, stop working for their dads' killer, and take swift action on him.
