Four young friends on a camping adventure are run off the road by an erratically driven road train - a massive three-trailer truck. With their own vehicle wrecked and the road train stopped, the friends march off to vent their anger at the driver. But the truck is empty. Suddenly, the silence is broken by the sound of gunshots. To escape, the friends commandeer the road train. What they discover inside the vehicle’s trailers proves more terrifying than anything out there on that lonely road. The next town is only three hours away, but will they reach it?
