Wendy, looking for a scoop for the newspaper, discovers Beauty dynamiting other stampeders' claims. She is about to stop him when a landslide from the dynamite exploding puts her in danger. White Fang hauls her out of the way, and they end up on a raft floating down the gating Yukon River. A logjam caused by the landslide not only puts Wendy and White Fang at risk, but also the steamboat that is chugging up river with supplies for Dawson. They must somehow save themselves and the steamboat from sure destruction.
