This film is a disaster film based on the "911" incident in the United States. The story recreates the sudden disaster at that time. On a beautiful morning on September 11, the Fire Department suddenly sounded the alarm. After receiving the news that the World Trade Center collapsed due to a terrorist attack, fire officer John McLoughlin (Nicolas Cage) and his colleagues immediately rushed to the scene. What lay before them was a series of tragic pictures, with the collapsed building emitting thick smoke and the injured people groaning in pain. In order to rescue the people trapped in the World Trade Center, John rushed into the building with his teammates regardless of the danger of the crumbling ruins. However, before they could take action, they were crushed by the second collapsed ruins. When John woke up in the rubble, he found that all his former companions who fought side by side had died, and only one police officer named Will Jimino (Michael Pena) survived. They waited for the rescue team in the hellish ruins. Facing the increasingly scarce oxygen and the death that could come at any time, fear, hesitation, sadness and despair slowly attacked from all directions. Rescue and self-rescue were carried out simultaneously in the thrilling 24 hours...
