On the morning of September 11, 2001, Colin, John, and Bruno return to their offices in the North Tower while Brian does the same in the South Tower. Jay has just finished his night shift and leaves his fire station 5 minutes away from the World Trade Center. Suddenly, the twin towers become the target of a ghastly attack. For the first time, the tragedy of September 11 is told through 5 survivors, 5 heroes, trapped on different floors in the hell that has become the World Trade Center towers. This is the story of their struggle for life.
