Thakur Singh discovers that his four sons, Shamsher, Ajay, Vikram and Vijay, are vile womanizers and drunkards. He changes his will to include his devoted servant Karan Singh. When his sons learn this, they kill him and chase down Karan to his home, where he is slaughtered and his wife Sharla is viciously raped and murdered by them. Their two children, Shabnam and Rahul are witnesses, and run away. They are separated, Shabnam taking refuge with the dreaded dacoit Mahadev, and Rahul being raised by a loving family. As an adult, Shabnam becomes a feared vigilante, hunting down the four men that killed her family. Rahul has grown to be an equally feared policeman, hunting down (unknown to him) his own sister.—L.
