Part husky/part wolf, Balto doesn't know where he belongs. He's an outcast in Alaska, except to his true friends--Boris, the Russian snow goose; polar bear cubs Muk and Luk; and the beautiful husky, Jenna.

When a fierce blizzard closes off all routes of transport, there's no way to obtain life-saving medicine...unless a team of sled dogs can race six-hundred miles through the blinding Arctic storm and bring back antitoxin.
