Wilbrook in Western Australia is a sleepy, remote town. All that changes when an injured man stumbles into Chandler's station. His name is Gabriel. He tells Chandler what he remembers. He was drugged, driven to a cabin in the mountains and tied up in iron chains. The man who took him was called Heath. Heath told Gabriel he was going to be number 55. His 55th victim. Trouble is, Heath tells exactly the same story about Gabriel ... Two suspects. Two identical stories. Which one is the truth?
