A wounded man walks into a police station in remote Western Australia and tells a remarkable story. Gabriel was picked up while hitchhiking, drugged, and woke up in chains in a barn in remote Western Australia. He'd been kidnapped by a man named Heath, who explains he's going to make Gabriel `number 55' -his fifty-fifth victim. Gabriel manages to escape and runs into the wilderness, eventually stumbling into town. The next day, a man calling himself Heath walks into the same police station and tells the exact same story. Except in his version, he is the victim. And Gabriel is the killer.
