Mangal dada (Sunil Dutt) is the local dada of the busti whom everyone fears yet respects as he always stands up against any injustice and is always there to help and protect them. He likes Lakshmi (Reena Roy), a resident of the basti and a street performer, though she is unaware of his feelings. Pratap(Amjad Khan), a businessman has been eyeing the land of the bastiwallas but knows that Mangal will be an obstacle. So he sends a few of his goons to beat up Mangal. The goons come across Lakshmi and start teasing her. Mangal happens to be there and starts beating them up and just when he is about to kill one of them, the police arrive and he is arrested. The judge sentences him for imprisonment for one year and five months. Once Mangal goes to jail, Lakshmi understands Mangal's feelings for her and she starts to miss him too. Mangal's sister Geeta(Farida Jalal) works in Pratap's house as a maidservant and doesn't like his younger sister Neetu(Sarika) getting too close to Geeta. At Neetu's birthday party, everyone is present except Pratap who is elsewhere in the house. Geeta is also present in the house, but not at the party. While passing by Pratap's room, he takes advantage of her and rapes her. Geeta tries to commit suicide but is prevented from doing so by Lakshmi. Geeta goes to Pratap, but Pratap does not evlilain her. Geeta knows that Mangal will finish off Pratap if he hears the truth and he will once again be behind bars. In order to avoid that she commits suicide by hanging herself. Mangal is released from jail and is shocked to find that his sister has committed suicide. He comes to know from Lakshmi that Pratap is the culprit and he decides to take revenge in a different way. The bastiwallas offer to help. But he refuses, saying that it is his personal business. He takes Pratap to an unknown location, threatens him and tells him that he would do exactly that to Pratap's younger sister what Pratap had done to his. From then on Mangal keeps on appearing before Pratap and he starts getting a little scared. Even Neetu, pratap sister boyfriend anil's elder brother that mangal is threating him. Mangal is taken to the police station and let off after the police ask him a few questions. On a particular occasion, Neetu meets with an accident while she tries to run away from Mangal. Mangal inform Pratap about the accident. Pratap again complains to the police officer, but the officer refuses to take action without proof. Pratap decides to take his mother and sister away to a haveli which they own at a hill station so that Mangal cant reach them. Mangal reaches the destination soon enough and after beating up Pratap's goons, he then ties up his Pratap and his mother. Then he proceeds to take advantage of Neetu , exactly the way Pratap had. Just then, Pratap asks him to stop and confesses to his crime. His mother and sister are shocked as well as ashamed of Pratap and Neetu is ready to give her body to Mangal. Mangal says that he did all that just to make Pratap confess and so he unties everybody. Just as he is about to go away, Pratap tries to kill him from the back, but is prevented in doing so by the police who arrives there.
