It is April of 1948 as Marty Toliver, her pilot husband, his father, and two children fly high above a snow-encrusted landscape. With their 1937 Grunman Goose airplane filled with camping gear and enough food to feed five people for two weeks, the family is more than ready for their adventure near a Calgary Lake. But when the plane encounters an unexpected storm, everything changes in an instant. Moments later, Marty crawls from the plane’s wreckage to find herself stranded in a mountain wilderness with two small children, completely unprepared for such a catastrophe. Marty is determined to do everything she can to keep her children alive in a desolate, cold, and unfamiliar environment. As she struggles with the strenuous tasks required to survive, she must rely on her novice hunting, butchering, and plant gathering skills. Soon, Marty realizes that rescuers are not coming; it is up to her to find a way out of the deep mountain valley and back home. But she is about to discover that her mission may be more difficult than she ever imagined. In this tale of survival, one woman must become what she has always considered savage in order to survive and keep her children alive.
