Description: The inhabitants of Forty Mile in Yukon, Canada are introduced during the 1890s Gold Rush. A caged Buck arrives and is promptly auctioned off as a sled dog. He makes an immediate impression on young Miles, who bids on Buck. However, Miles is outbid by The Swede, who uses Buck on a sled team delivering mail throughout the Yukon. As Buck heads out on the trail with The Swede's team, he makes an enemy of Spitz, the team's vicious lead dog.
