A mentally fractured and hideously powerful spirit of a Georgian plantation and slave owner hold in thrall the men and mounts of a Civil War foraging party. She is avenging the death of her husband and children by putting the enemy spirits through a daily ritual of Hell. Ryan Fitzgalen was rendered spiritually clairvoyant and caused to be the world's oldest man by a WW II experiment using electromagnetic power for naval stealth technology. He and the spirit of his deceased wife, Vanessa, are no match for Mad Annie, and so must call in his distant descendents to even the playing field. Even then, one of the Fitzgalen Family must fall.
