A group of "ghostly" conquistadors has been robbing towns along the Mexican border. West and Gordon follow their trail across the border to San Pedro, where they learn that the raiders are using a secret pass in the mountains to reach a hidden valley. Upon riding out there they encounter and rescue Juan Ramirez and his daughter, Cosina. The two are residents of Buena Vista, a town in the hidden valley which sits in the shadow of a volcano inhabited by the conquistadors and their leader, the white "god" Cortez. Cosina guides the agents to the village and they set about ending Cortez's reign of terror.
