Cheyenne is riding along the trail when he is almost bushwhacked by two strangers. The person who saves him is a marshal, Frank Moxon, with a reputation for getting his man. Cheyenne has nothing worth stealing but Moxon tells him the men confused Cheyenne with Moxon as they are about the same build. They ride together with Cheyenne deciding to accompany Moxon to South Fork. Cheyenne shoots a rattlesnake threatening Moxon. After seeing his skill Moxon decides to employ Cheyenne as a deputy to enforce an old warrant. They are in town to pick up John Sevier wanted for the murder of a man in Abilene, Kansas. The man is well respected in South Fork as a carpenter who has built a good life. Cheyenne quickly learns that Moxon may be a law officer but he is known as a bounty hunter who never returns a prisoner alive. Paul Caldwell, an ex-sheriff Cheyenne knows, confirms it and is goaded into a gunfight with Moxon which Caldwell loses. The tables are turned on Moxon by the local sheriff, the townspeople and especially Cheyenne who makes a promise to Mrs. Savier.
