Shakti Singh is a poor, hardworking boiler mechanic who lives a happy life with his wife Seeta, mother, and two sons, Arjun and Vijay. Shakti always falsely fights against injustice. Once he is falsely implicated for this, and he has to go to jail. Seeta is forced to be a courtesan instead of the money owed by Shekhar, so a misunderstanding creates a rift between Shakti and Seeta; insulted Seeta leaves the house. Shakti realises his mistakes, but it's too late; soon, he takes to crime and becomes an underworld don. After some years, his two sons, Arjun, are married to Kajal and Vijay to Aarti. Kajal does not like his father-in-law as he is involved in illegal activities; Arjun is self-employed; Vijay has some bad habits for which he often quarrels with his father. Shakti has enemies and traitors in his business. The situation worsens when Vijay is killed.
