A shocking and gruesome murder wakes an ancient evil in outback Australia. A truck driver, a schoolboy, and a retired couple on their dream holiday are among a group of travelers caught up in a supernatural time loop. Trapped on a long stretch of the Silver City Highway, just outside Broken Hill, they enter a nightmarish journey from which there seems no escape. Following the gruesome discovery of the bloodied and battered bodies of a young woman and a man on a property not far from the highway, the truck driver is forced to confront the very real possibility that there is a killer on the loose and then convince his fellow travelers that they are all in danger.
