Engine 10 and Ladder 10 of the FDNY are housed together in a building that was literally yards from the South Tower of the World Trade Center. Their firehouse is known to New York’s firefighters as either "10x10," or "Ten House." On 9/11 it was the firefighters of Ten House who were the first to enter the Twin Towers and the last to leave. On that day, six men lived and six men died. This is the dramatic and inspirational story of the heroism of the fire-fighters of Ten House on 9/11.
