Dr. Ram Prasad Ghayal, Amitabh Bachchan, is a renowned doctor who has earned a spotless reputation for flawless operations and a steady hand in the operating room. He shares his life with his wife Mrs. Janki Ghayal, Dimple Kapadia, and his brother Bharat, Arbaaz Ali Khan. Bharat is secretly in love with Renu, Karisma Kapoor, the daughter of Umeshchan Jain. Meanwhile, Raja Tonga, the brother of Rana Tonga, harbors his own longing for Renu. When Raja makes a crude attempt to press his advances toward Renu, Bharat stands up to him, and the confrontation ends with Bharat being brutally assaulted by Raja and his mob.
A corrupt minister, Mohanlal, schemes to push through a disastrous project called the “Pawanghat Power Project” that would devastate tribal lives and lands at the project site. He pressures Bharat, the concerned engineer, to sign off on the plan, but Bharat refuses to endorse such a scheme. In the shadows, Rana Tonga quietly plots to eliminate Bharat so that Raja’s chances with Renu improve. Bharat is framed for the murder of a woman, and Inspector Danapani, a corrupt subordinate of Rana, arrests him and puts him behind bars. Tragically, Bharat dies in jail, seemingly by suicide, and the heartbreak also takes the life of Janki from the shock. With the loss of his wife and brother, Dr. Ram descends into despair and alcoholism, and Renu ultimately marries Raja, seemingly without any remorse for Bharat’s death.
With Bharat out of the picture, Mohanlal and Rana drift into a bitter feud over the fate of the power project. Mohanlal’s plan shifts toward killing Raja, and his henchmen launch an attack that leaves Raja critically injured. Raja is rushed to the hospital where Dr. Ram is scheduled to operate. Renu fears that Dr. Ram might perform the operation to avenge Bharat, and she refuses to sign the papers. Yet Dr. Ram, bound by a physician’s duty to save a life regardless of friendship or foe, proceeds with the operation. The surgery is a success, and Raja survives, only to be killed later when Ram discovers Raja’s death beyond his expectations. In response, Renu files an F.I.R. against Dr. Ram, who is arrested.
While imprisoned, Dr. Ram meets an inmate known as 92, Prof Nizamuddin Azad, Rama Krishna, a scientist from Bharat Atomic Energy who has been jailed on false charges of leaking confidential nuclear formulae. Azad reveals that Bharat did not commit suicide but was tortured to death by Insp. Danapani, a revelation that reframes Ram’s understanding of his own misfortunes. Fueled by the truth, Ram embraces the mantle of the Angel of Death, Mrityudaata, vowing to bring down those who tried to harm the nation.
Escaping from custody, Ram tracks down Insp. Danapani and learns that Mohanlal had schemed with Rana to murder Bharat. Danapani’s own fate comes when Ram pushes him from a building to his death. Ram then corners Dr. Rahim Siddiqui, Avtar Gill on the rooftop of Umeshchan Jain’s house; Siddiqui confesses to killing Raja and accepting a bribe from Mohanlal, a confession Ram records before carrying out Siddiqui’s death. Ram’s next target is Mohanlal, whom he eliminates.
The tension reaches its peak when Trilochan Tripathi (TT), the esteemed but morally compromised politician also known as the Terror of Terrors, takes center stage at a public rally. Ram unleashes a damning video that shows Tripathi sealing an agreement with a foreign syndicate tied to the Pawanghat project. Tripathi’s carefully crafted image collapses as the crowd erupts in fury, chasing him through the streets. Rana Tonga arrives in a bid to rescue his ally, but a gunfight erupts and Ram is shot. In a final act of reckoning, Ram survives long enough to burn both Rana and Tripathi to death.
The story closes on a somber note as Dr. Ram succumbs to his injuries, having set in motion a chain of truths and takedowns that expose a web of corruption and motive behind Bharat’s death and the perilous project that threatened countless lives.
