Alex (Kate Winslet) is desperate to head back to New York in time for her wedding, while Ben (Idris Elba) needs to return to operate on a young boy. However, all flights from an Idaho airport are cancelled due to an incoming blizzard.
Alex and Ben hire agree to hire a small plane, but not long after takeoff the pilot Walter (Beau Bridges), suffers a stroke and crashes the plane on a mountain, leaving them stranded with only the pilot's dog to keep them company.
With no cell phone reception and all devices out of commission, Alex and Ben realize that help is not on the way. Alex wants to take their chances on foot, while the more conservative Ben is less inclined to leave and wants to stay put.
When Alex looks through her camera lens and sees a metallic glint off in the distance, they embark on a perilous journey across hundreds of miles of wilderness, pushing one another to endure and discover their inner strength.
