Jagmohan Jugral kills his twin brother, Manmohan, to assume his identity and escape his criminal past, but his deadly web of deception is only just beginning to unravel. When Customs Officer Verma becomes suspicious of Jagmohan and starts to investigate his activities, Jagmohan decides to eliminate him and takes the life of Dr. Ashok Soni as well. This results in the orphaned children of the slain pair, with Ramesh and Seema, now seeking revenge on Jagmohan, now disguised as a respectable citizen. As they mature, Ramesh learns the art of thievery from his new 'father,' Girdharilal, while Seema thrives in a respected household. The two siblings plot separately and come together to take down Jagmohan and his wicked ways.
