Stranded on a mountain after a tragic plane crash, two strangers must work together to endure the extreme elements of the remote, snow-covered terrain. When they realize help is not coming, they embark on a perilous journey across hundreds of miles of wilderness, pushing each other to survive and discovering their inner strength.
