A deadly confrontation ensues between the police and the terrorists, resulting in the deaths of several police officers and five of the terrorists.

As the news of their hideout spreads through the media, it causes panic among the families of the hostages, who gather outside the clinic. The police and commandos surround the building, but the terrorists issue a chilling warning: any attempt to enter will lead to the execution of hostages. To prove their ruthlessness, they leave several dead bodies outside the gate and display their modern weaponry.

The terrorists demand that the Chief Minister withdraw all police and military forces within the next hour, threatening to kill everyone in the clinic if their demand is not met. Tensions escalate when the terrorists discover that the son of a high-ranking officer is among the hostages. With little time and the odds against them, the police and commandos must devise a strategy to resolve the crisis.

What happens next? Does the police rescue the hostages? The climax builds up the suspense, leaving readers on edge.
