Do you remember where you were when two jets plowed into the World Trade Center buildings? If you were at ground zero, you have a particularly harrowing story to tell. But that day affected most people no matter where we were. For the people who then navigated boats on the Hudson, their peaceful everyday world became a rescue operation. In interviews afterwards they shared the compelling drive that led them to improvise, regroup and help 10s of thousands of people get off the island of Manhattan, often at risk of their own lives. In gripping detail we learn their stories and also get confirmation of the best in us as human beings; the call to help when we see suffering.
