Butch Cassidy and the Sundance Kid, along with their gang, the Wild Bunch, pulled off one of the greatest train heists of all time. To discover the real story behind the legend of the great train robbery, Bat Masterson sits down with Etta Place, the former girlfriend of the Sundance Kid. In 1899, the Wild Bunch, successfully robbed the Union Pacific Overland Flyer train right outside Wilcox Wyoming. Using Union Pacific regulated lanterns to flag down the train and blowing up a bridge to stop a posse from following them, they were able to get away with $30,000 in cash and gold, going down in history as one of the most successful gangs in the Wild West.
