Based on a Rocky Mountain legend, Stone Fox tells the story of Little Willy, who lives with his grandfather in Wyoming. When Grandfather falls ill, he is no longer able to work the farm, which is in danger of foreclosure. Little Willy is determined to win the National Dogsled Race—the prize money would save the farm and his grandfather. But he isn't the only one who desperately wants to win. Willy and his brave dog Searchlight must face off against experienced racers, including a Native American man named Stone Fox, who has never lost a race.
