After giving up his gunfighting ways, Billy Ringo (George Montgomery) has settled down with his new wife, Arlene (Helen Westcott), on a ranch he's just purchased with his brother, Matt (John Dehner), and nephew Chip (Tab Hunter). But when Matt tricks him into participating in a bank robbery -- and frames him as the ringleader -- Billy is forced to go on the run from lawman Wyatt Earp (James Millican), and once again take up his guns against his former rival, Ike Clinton (William Bishop).
