n a secret lab hidden within the heart of Mumbai, Dr. Arvind Rao develops an experimental serum capable of reviving the dead—if administered within a precise time frame. His breakthrough is meant to revolutionize medicine, but when a test subject, a deceased convict named Raghav, is injected with the serum, an unforeseen mutation occurs. Raghav awakens with unnatural strength, rapid healing, and a bloodthirsty instinct beyond human comprehension.
As Raghav's killing spree spreads across the city, Inspector Karan Mehta is assigned to stop the seemingly invincible murderer. With each attempt to destroy him failing, Karan realizes that conventional methods are useless against a being that refuses to die. As the city plunges into chaos, Arvind must confront the horror he has unleashed.
In a desperate bid to end the nightmare, Karan and Arvind track down Raghav to the abandoned ruins of an old military research base. But as they prepare for a final confrontation, they discover a terrifying truth—the serum did more than revive Raghav. It awakened something ancient, something beyond science.
