A family--a mother, a father, and their ten-year-old son--have come all the way from Florida to the Appalachian foothills to experience the wonder of a snowy weekend. At a nearby farm, a cattle dog is working, as she does every day, driving her forty head of cattle from pasture to corral and back again. And then, suddenly, a blizzard descends. The family is trapped outside, disoriented in the whiteout. They are panicked, exhausted, freezing, and stranded in waist-deep drifts. From off in the distance, the cattle dog has heard their faint, snow-drowned cries. Her inexhaustible attention turns to saving them. This stirring tale is both a compelling story of survival and a meditation on the tremendous will of man's best friend.
