Fear on the Sacramento Mountains! Tex and Carson run into a group of terrified miners, run away from the mining center of Bendito to escape the Great Snake, a horrible humanoid reptile. The rangers head for the town to investigate and in a climate of great tension, they discover that the miners, recently joined in partnership, are bound by a lousy deal: whoever leaves before six months have passed doesn’t get even an ounce of the extracted gold! Meanwhile, slipping out of a fetid hole opened in the rock, a monstrous sorrel wanders around town during the night, spreading death and horror.
