Little Willy's grandfather is sick, and it's up to Willy to save their farm from tax collectors. Their only hope is the prize money from the National Dogsled Race. But a lot of other people want to win the race, too, including Stone Fox, who has never lost a race in his life. Do Willy and his dog Searchlight stand a chance against the toughest racers around? Can they win the race to save the farm -- and Grandfather -- before it's too late?
