Two strangers headed from Salt Lake City to Baltimore -- one a surgeon who has to perform an operation (Idris Elba), the other a photojournalist who's about to get married (Kate Winslet) -- hail a chartered flight together after their initial travel plans fall through. Unfortunately, they end up stranded on a snowy mountain when their plane crashes, and soon realize they must trek to safety since no one is coming to rescue them. Based on the novel by Charles Martin. Directed by Hany Abu-Assad.
