Wild Bill Jones is saved from three toughs by “Silver Jim” Donovan, a newcomer to Winchester. They team up to campaign for Thad Morgan for state senate running against crooked incumbent Walter Kincaid. Morgan’s campaign is headed by saloon owner Queenie Canfield. Jim visits Doc Winslow and asks him to keep on the lookout for a man with a jagged scar on his left arm, as a man so-marked had shot Jim’s father in the back with a silver bullet which Jim now wears as a watch fob, with full intentions of returning it to the former owner. Kincaid has Morgan killed, and Jim, Nancy Lee and others now campaign for Morgan’s widow, Emily.
