Mayle Stone, a young fur trapper, lives with Izusa, a Cherokee woman whom he received as 'payment' for a wolf skin from a Cherokee brave. During a visit to Fort St Vrain for supplies, Izusa comes to the attention of an outlaw, Jon Rudyman, who plans to kill the trapper and take the woman. The plan has flaws, however, and Stone survives, but Izusa disappears. Henceforth Stone is out for revenge. But also looking for Rudyman is Bounty Hunter Rey Heston. It's a race to see who will track down Rudyman first.
