A crazy scientist arrives in Dawson with a gold detector and claims of a gold mountain that can be found in the far North. Weedon forms an expedition to cover the story, but won't bring Wendy along. But a sneaky De Lazlo follows the expedition and hauls Wendy along for ransom. White Fang also follows and frees Wendy from De Lazlo's clutches. Meanwhile, De Lazlo, not one to give up easily, traps Matt, Wendy and White Fang on an ice flow. An Eskimo rescues them and convinces them to do the right thing. They must all stop De Lazlo and convince the expedition team that the sacred mountain must be left alone.
