Despite his apathy toward white folk, mountain man Joe Fox reluctantly agrees to lead a group of settlers through the Rockies to Oregon. Taken aback by their appreciation, he soon finds himself enjoying their company - especially the attentions of young Callie Simmons. That is , until her parents warn Joe to keep his distance. But they should have worried about Max Starbeau. A wolf in sheep's clothing, he travels with the party until the opportunity arises to steal and murder - and then to kidnap Callie for good measure. When the settlers find themselves unable to track Starbeau, they once again turn to Joe Fox - who owes them nothing but will do anything to save Callie.
