s. 1, ép. 1: On October 12, 1967, combat photographer Cpl. William T. Perkins, Jr. made the ultimate sacrifice when he hurled himself on an enemy hand grenade to save the lives of his fellow Marines. 30 years later, his friend Craig Ingraham set out on a journey to discover what happened that day in Vietnam. Perkins is the only combat photographer in our nation's history to receive the Medal of Honor.
