Zero Hour dramatizes the hour leading up to some of the most memorable historical events as they unfold minute by minute. Using a real-time clock and a split screen to follow key players, the series reveals the compelling and exciting minutes leading up to events that changed the world. The focus of the series isn't the event itself, but the individual moments that culminate in the actual event. By following numerous theatres of action as the clock winds down to zero hour, viewers are put right into the moments leading up to major historical events. Most history programming is done with 20/20 hindsight. The aim of ZERO HOUR is to experience history just before it became history.
