Gideon, Tallie, and Joshua travel to Arizona Territory searching for Rollie Anderson, a murderer and thief. Before they can search for Anderson’s hideout near the Mogollon Rim, two bounty hunters get on Joshua’s trail. In the meantime, Anderson steals several wagon loads of gold from the Vulture Mine near Wickensburg. Somehow, he finds out about even secret shipments and stops them. It’s up to Gideon and the others to find out who is giving him information and stop them, along with capturing Anderson. If Joshua can get away from the bounty hunters after him, that is.
