This episode tells the harrowing story of how two students and a professor at Virginia Tech University managed to survive the April 16, 2007, massacre at the school. One of the students, Colin, had to lay motionless and play dead as the gunman shot him four times. We also chronicle the amazing story of the Minneapolis school bus with 52 children that plummeted 45 feet when a Minneapolis bridge collapsed in August 2007. Trapped in her seat, driver Kim held the brake, keeping the bus from rolling backwards, as counselor Jimmy and his co-workers rush to evacuate the children, including Kim’s own daughter.
