Cheyenne comes upon a campfire in the basin. He meets a young man, Bill Paxton, who jumps him suspicious he could be a rustler. When he takes Bill's gun and rides off he is surprised to hear screams from where he just left Bill and goes back only to find he has been crushed to death by something that also doesn't seem to like campfires. When he takes the body into town, Cheyenne discovers there is a twin brother who is now looking for revenge for his death! Cheyenne takes a job with rancher Jim Harwick. The other ranchers complain that Harwick has not sent someone to help look for the rustlers as he has not been hit so far so Harwick decides to give the job to Cheyenne as the last man hired. Cheyenne agrees to take the job scouting the basin for the killer and rustlers. In the basin he runs into Dr. Raven and his daughter Sherry who is engaged to Bill's twin brother Pierce. That night he rescues Sherry who was knocked from her horse. Later, he is ambushed by Pierce. Cheyenne believes he can trust Pierce so he reveals his real mission.
