Suraj Singh (Shatrughan Sinha) lives with his widowed mother Padmini (Moushumi) in a small hut in a Bombay city slum. He cannot stand injustice in any form, and this places him in the bad books of Police Inspector Shankar (Dharmendra). One day Suraj comes across an older man Zorawar (Dharmendra in a double role) and brings him home. What Suraj does not know is that Zorawar is a former jailbird, who has completed his sentence, for multiple murders and alleged rape of a woman named Gauri (Jayaprada). Although Gauri is no longer alive, the vow to avenge her rape and death is kept alive by her Police Inspector brother (Vinod Mehra). To complicate matters further, Suraj finds out that his mother is having an affair with Zorawar. What does Suraj do under these circumstances?
