In this season, the trio starts their journey with Gettysburg, Pennsylvania, at three different lock-down locations of the Gettysburg Battlefield. Part one takes place at the Soldiers National Museum, a former American Civil War-era orphanage where it is claimed that children were abused by a matron. Part two takes place at the Jennie Wade House, where Jennie Wade, the only civilian casualty in town, was killed in the kitchen by a stray Confederate bullet. Part three takes place at the Engine House, where the first battle of Gettysburg occurred.
