One Friday afternoon, Steve and Mark Cross head off on an adventurous father and son weekend in the Australian bush. The long drive provides plenty of time to shake off the weekday woes, have a few laughs and soak up the rugged landscape. In the early hours of the morning, as they near their destination in a remote part of the country, through the endless darkness of the ‘night highway’, they notice a dull light on the road up ahead.As they get closer to the light, it becomes painfully apparent that something is not right. What unfolds from that point will see Steve, Mark and others, encounter a group of locals who subject them to sinister and relentless demands, over and over. If they are to survive, they’ll need to push themselves beyond all physical, mental and emotional boundaries. Either way, life will never be the same.
