The year is 1925. It is sixty degrees below zero. The wind sweeps tons of snow over the deep-frozen Alaskan landscape. The nearest railhead is seven hundred miles away. Airplanes cannot fly. The way to Nome is blocked by a treacherous frozen sound, an icebound port, and mountains to the west. But there is a diphtheria epidemic in Nome. The children need serum from the outside world if they are to survive. Their only hope is a few chosen Eskimo drivers and their teams of dogs, who must make a relay race across the wilderness if the serum is to get to Nome in time. The heroism and stamina of the men and their dogs can only be called legendary. Now, their story can be told.
