Three men trapped in an elevator in the north tower on 9/11 reunite to thank one of the building’s window cleaners, whose last-minute entry into the elevator helped them all survive.

As first responders rushed to the World Trade Center on September 11, a hijacked plane hit the Pentagon. An Army corporal, who jumped from a window before she succumbed to smoke inhalation, reunites with the Navy SEAL who caught her.

After the collapse of the south tower, a firefighter worked with a police officer who later lost his life. The firefighter meets the officer’s family to tell them he was thinking of them in his final moments.
