Balto

Balto was half wolf and half Siberian Husky. In 1925 in a city called Nome, in Alaska, an epidemic broke out and they needed one million units of antitoxin. The nearest buffer stock was 1700 km distant and there weren't efficient communication channels. The only way to take the antitoxin to Nome were the sledge dogs and a relay was organized. Balto completed the relay and begun famous.
