Now a film starring Idris Elba and Kate WinsletWhat if your survival depended on a stranger? On a stormy winter night, two strangers wait for a flight at the Salt Lake City airport. Ashley Knox is an attractive, successful writer, who is flying East for her wedding. Dr Ben Payne has just wrapped up a medical conference and is also eager to return home. When the last outgoing flight is cancelled because of a storm, Ben charters a small plane that can fly around the weather front. And when the pilot says the single engine prop plane can fit one more passenger, Ben offers the seat to Ashley. Then the unthinkable happens and the plane crashes into the High Uintas Wilderness. Ben, who has broken ribs, and Ashley, who suffers a terrible leg fracture, along with the pilot's dog, are faced with a battle to survive. How will they make it out of the wilderness and if they do, will they ever be the same again?
