Sherlock, an egocentric businessman in Los Angeles in 2011, is about to fire his secretary, Sophie. But when he walks into an elevator in the skyscraper he works in, he finds himself travelling back in time to the moment when the first plane is about to hit World Trade Center One on September 9, 2001. His actions during the tragedy in the famous Windows on the World restaurant transform him into a man who is caring and heroic. This gripping story is about those people who were left to die, and how an interloper from the future succeeded in saving a few. It is, most importantly, about the brave efforts of those who struggled to save the people in the towers, and the challenges they faced on this horrible day in New York City.
