The Gambler Wore a Gun, directed by Edward L. Cahn, is a high-action, dramatic western of the 1960s that follows the story of Case Silverhorn (Jim Davis). Case, a professional gambler, purchases a ranch via post. However, an individual murders the ranch seller before the deed to the land can pass into Case's hands. The ranch owner's children, Sharon (Merry Anders) and Jud Donovan (Don Dorrell) refuse to vacate the ranch due to their lack of knowledge of the sale. This forces Case to find work at the local saloon. Through his work, he finds out that rustlers have used the ranch-lands to illegally store stolen cattle. When Jud Donovan learns of the operations occurring, the gang kills him. Resultantly, the gang frames Case for the murder. This throws Case into an unwanted, renegade status as he tries to uncover the truth while fighting the gang and fleeing the law.
