In Civil Dread, a team of retired military veterans, now paranormal investigators, trades the battlefield for a new kind of war. Based in Florida, they head to a notoriously haunted Civil War fort in Georgia, where they soon discover that the terrifying hauntings are not from lingering spirits, but from a malevolent demonic entity. Teaming up with a seasoned demonologist, this band of brothers must draw on their combat skills and newfound supernatural expertise to face their most dangerous enemy yet and save the fort's tortured souls.
