Ten-year-old Willy is facing the race of his life. It's more than just a 10-mile dogsled race through the frozen Wyoming countryside. The $500 grand prize will save the family's potato farm and possibly his grandfather's life. It won't be easy. Also competing is Stone Fox, the mysterious and legendary Shoshone Indian mountain man who has never lost a race. Stone Fox uses his race winnings to buy back Shoshone tribal land in Utah. Both Little Willy and the giant Stone Fox race for noble causes, but only one can win.
