This is the inspiring true story of Leonhard Seppala and his lead dog, Togo. Leonhard Seppala came to Alaska in 1900. He learned to run a dog team and within two years had become an expert dog musher. When a tiny, sickly puppy named Togo was born in Leonhard's kennel, no one expected the puppy to live. He didn't die. When he was just eight months old, Togo made Leonhard's team and became his favorite lead dog. In 1925 a deadly diphtheria epidemic threatened Nome, Alaska. Life-saving serum was hundreds of miles away. The only sure way to get the serum to Nome was to relay it across Alaska using 20 dog teams. Togo bravely led his team through raging storms, over the longest distance, across the most dangerous part of the relay. Togo, the little dog no one expected anything of, helped save Nome and became a hero.
