 After deviously getting his step-brother out of the way, Jagatpal (Ajit) manipulates his sister-in-law (Urmilla Bhatt) to sign the estate away to him, which she does, and is subsequently thrown out, leaving two boys in the care of Jagatpal. The two boys have grown up to fear and obey their uncle, Balram (Amitabh Bachchan) is now a police inspector, and Bholuram (Dharmendra) is a motor mechanic. Bholuram and Balram continue to acquire wealth, by hook or by crook, for their uncle. In so doing, Bholuram incurs the wrath of Chandan Singh (Prem Chopra) and Suleiman Seth (Amjad Khan). In the meantime Balram has fallen for Shobha (Rekha), and Bholuram for Madhu (Zeenat Aman), little knowing that Madhu is the daughter of none other than his uncle, Jagatpal.
