Justin Kirkbride is a pilot in training, but when he takes two friends, Tommy and Larry, on a sightseeing tour of the Rocky Mountains, he finds himself in the test of a lifetime. The plane crashes on a steep, snowy mountainside. With both friends badly injured, Justin decides to hike 45 miles down the mountain in search of help. While he's walking, he manages to hail a rescue helicopter by cell phone, and he joins the rescue pilots to search for his two missing friends. But then disaster strikes again: the rescue helicopter clips a tree and smashes into the mountainside. Can Kirkbride escape with his life for the second time in 24 hours? And will his injured friends survive the night?
