SSP Amar Nath Singh breaks into the fortress of criminal Goga, bashes him up, and arrests him. Incidentally, Goga was the one responsible for Amar's separation from his parents Hardayal and Shanti Devi. He takes him to the police headquarters where he commits suicide. But he comes to know that Goga has a son Brijbhan who is now a high-profile criminal with whom several police officers and Indian army officers are working to spread terrorism in India. Also, Brijbhan has kept Amar's childhood sweetheart Shalu in his captivity as his mistress. To stop them, Amar wants to unite two warring gangsters Karim and Harihan who are constantly at loggerheads with each other due to their different religious backgrounds. Both of them regard Amar as their elder brother. Karim is in love with a girl named Salma.
Karim is a powerful and respected gang leader, but he is also driven by deep-seated hatred and rivalry. For years, his life has been defined by his intense and violent feud with Hari, a conflict fueled by their different religious backgrounds. Karim’s identity and actions are inextricably tied to this animosity, and he is unable to see a path beyond their constant clashes.
The story shifts when Inspector Amar uncovers a massive criminal conspiracy led by the influential underworld don, Brijbhan. Recognizing the futility of fighting this formidable enemy alone, Amar finally devises an unconventional plan: he decides to unite the two warring gang leaders.
Amar’s main challenge is to convince Karim to set aside his hatred. He approaches with an appeal to his humanity. He shows Karim how Brijbhan’s criminal activities are indiscriminately harming innocent people and creating chaos, far beyond the scope of their personal rivalry. Karim understands that while their feud has been a source of violence, it is Brijbhan's actions that are a direct threat to the very fabric of society. Initially, Karim is resistant to the idea of an alliance, unable to let go of his long-held animosity toward Hari. However, through Amar's persistent efforts, Karim begins to see the bigger picture. He realizes that his rivalry with Hari has been a distraction, blinding him to a far more dangerous and destructive enemy. They forget all their differences and resolve to continue the battle between patriots and terrorists. They get hold of corrupt police officer Lotaram who is on Brijbhan's payroll, and extract a lot of information regarding Brijbhan's plans to spread terrorism. Concurrently, Shanti Devi finds out that Amar is actually her long-lost son, and goes to meet him in prison. Also, at the same time, Shalu manages to escape Brijbhan's captivity. She meets Amar in jail, and the two long-lost lovers have an emotional reunion. However Brijbhan, in disguise, manages to capture Shalu again.
At the time when Amar was being taken to the gallows to be hanged, Shalu, having lost all hope of being with Amar, consumes poison. Having somehow anticipated this, Amar makes a dramatic escape from the gallows and goes into hiding. On the way, he runs into his little sister Munni, who, owing to the recent events, had lost her mental balance and had become insane. Karim, with help from Hari, invades Brijbhan's fortress and begins decimating it. Salma uses herself as bait to trap a high-ranking army officer, who is killed by Karim. The poison's effect begins to show as Shalu collapses while dancing for Brijbhan. Shanti Devi begins to madly beat a drum to satisfy Brijbhan.
At the same time, Amar arrives with Munni, and a full-fledged fight ensues. Many of the terrorists are killed. Seeing this, an enraged Brijbhan fires at Shanti Devi, but Amar comes in between and is shot. Brijbhan kidnaps Munni and escapes. Amar gives chase, in the course of which he gets shot a few more times. He manages to catch up though, and rescues Munni. He brings Brijbhan back to his fortress and leaves him to be killed by Karim and Hari. Brijbhan meets his end at the hands of the duo.
Amar collapses due to his wounds. Shanti Devi begs him not to die, as she had already lost a son once. He assures her that Karim and Hari will take care of her and then dies.
