In the two-part season premiere airing over two consecutive weeks, Josh Gates and Heather Amaro venture into the haunted ruins of Spike Island, once Ireland's most infamous, brutal prison. Drawn by claims of frightening paranormal activity from both visitors and inmates alike, the team investigates whether centuries of torment and suffering inside the fortress' walls have unleashed something sinister. With an ominous presence underfoot, the search for answers leads them on a harrowing investigation through the prison's grim cellblocks and terrifying labyrinth of tunnels.
