This gritty and intense family drama is sparked off when Deputy Superintendent of Police Shamsher Singh (Shammi Kapoor) captures the notorious bandit Mangal Singh (Amjad Khan) just as Mangal's wife is about to give birth. She dies at childbirth, but not before extracting from the DSP his promise to take care of her son.
Subsequently, DSP Singh raises the boy alongside his own. Though ironically, DSP Singh's natural son Kishen (Vinod Khanna) has a wicked streak, while Mangal's son, Amit (Amitabh Bachchan), is endowed with an honest nature.
Released after 14 years in jail, Mangal finds out that his son is with his old enemy. He mistakes Kishen to be his son and instigates him to fight against Shamsher's family. They join the underworld gang and spread havoc. Amit becomes an honest police officer and is assigned the task of nabbing the gang.
After a misunderstanding, Kishen comes to believe he is actually Mangal's son and falls under the bandit's influence, though he continues to live in the inspector's home. What will happen when the misunderstandings are clarified and the truth that Amit is actually Mangal's son is revealed?
