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 much anticipated wedding. Dr Ben Payne has just wrapped up a medical conference and is also eager to return home to Jacksonville, Florida for a slate of surgeries he has scheduled for the following day. When the last outgoing flight is cancelled due to a broken de-icer and a forthcoming storm, Ben finds a charter plane that can take him around the weather front. And when the pilot says the single engine prop plane can fit one more, Ben offers the seat to Ashley.
Then the unthinkable happens. The pilot has a heart attack mid-flight and the plane crashes into the High Uintas Wilderness - one of the largest stretches of harsh and remote land in the United States. Ben, who has broken ribs, and Ashley, who suffers a terrible leg fracture, along with the pilot´s dog, are faced with an incredibly harrowing battle to survive. Ben records messages to his beloved wife on a small tape recorder; seeing his devotion, Ashley wonders if she has rushed into her engagement.
As the days on the mountains become weeks, their survival becomes increasingly perilous. How will they make it out of the wilderness and if they do, how will this experience change them?
