Vivaan Ahuja, a skilled MMA trainer, learns that his wife Anshika Maitra's heart can stop at any time and an operation is required. The operation is successful. As Anshika recovers in the hospital, a terrorist group led by Saju Solanki attack the hospital to retrieve their illegal arms dealer and leader Ajay Pal Singh, who was actually responsible for the deaths of 18 INA soldiers due to his supply of faulty weapons and was moved to the hospital for emergency surgery after his pacemaker was tampered in prison. The hospital patients are taken hostage, including Anshika, while Ajay is unconscious under anesthesia after his surgery. ACP Jayati Bhargav and her team are tasked to free the hostages.

Vivaan, who is just leaving after visiting Anishka is in the hospital basement, oblivious to the invasion until he is attacked by one of the terrorists, where he manages to kill him. Shocked, Vivan takes the black pouch belonging to the terrorist, which contains a walkie talkie and a remote detonator and sneaks back into the hospital. Vivaan meets a hospital guard named Riyaz and a child named Zubin who had been hiding, and befriends them. Jayati is stunned to see that her daughter Aanya is being used by the terrorists, strapped to a bomb. Saju blackmails her, saying that he will blow up the hospital unless she supplies a chopper and a bus to them. Jayathi agrees, but secretly plans to attack them.

Vivaan learns about the hospital's layout with Riyaz's help and plans to attack the hospital's control room so that Saju can't see him coming. Vivan is attacked again but with Zubin's help, he kills the terrorist. The bodies of both terrorists are found and Saju orders Vivaan to be killed. Vivaan manages to contact Jayati intermittently and informs her about Saju. Vivan continues to kill and evade the terrorists stationed around each floor and is finally able to take control of the control room with Riyaz and Zubin. Vivan frees the patients held hostage on the ground floor. Saju, who is on the ninth floor realizes that Vivaan is related to one of the hostages and tries to figure out who it is. Unable to do so, Saju kills a nurse to force Vivaan out of hiding. Ajay wakes up and they plan for their escape.

Vivaan realizes during a conversation with Riyaz that Saju was lying to the police; he was never going to use the bus and chopper he had demanded, but rather escape through the sixth floor. He is actually planning to blow up the stairs and the elevator in order to erase evidence by killing the hostages. Vivaan relays this to Jayati, who decides to trust him and play by his information. Jayathi and her team enter the hospital where they free Aanya and deactivates the bomb. Vivaan kills Saju's accomplice and finally defeats Saju. Saju is eventually killed after the falling elevator collapses on him, and Jayati shoots Ajay to death. Jayati thanks Vivaan for his help, remarking that he should be given a medal for his work but respects his wish to keep his identity away from the media.
