Calavera

On the Kaibab Plateau, in Arizona, an Indian archer skewers Paul Scofield, an outlaw who is wandering through the snow with his dog. The pards recover the little animal and are attacked by the gang of extortionists who are rampant in Mike Creek, led by Nick "Calavera" Guerrero. Scofield had stolen an old Indian map from the gang that marks the location of a legendary goldfield and Guerrero is convinced that Tex and Carson know something about it. The gang is immediately eliminated, but Nick doesn't give up and, to hunt down the rangers, he allies himself with the desperados of El Tigre.
