The Johnny Mack Brown West of Wyoming concerns the efforts by cattle baron Simon (Stanley Andrews) to prevent the opening up of the rang to homesteaders. Government agent Brown comes calling when Simon begins resorting to cold-blooded murder. The leading lady is Gail Davis, a few years shy of her Annie Oakley TV stardom. Surprisingly, West of Wyoming contains none of the comedy relief that had characterized earlier Johnny Mack Brown oaters.

Wild Bill Elliot plays gambler Frank Graham, who heads to Kansas in search of his father's murderer. This being 1864, the local military presence is more preoccupied with keeping Southern sympathizers out of the state to worry about Graham's problems. Thus, our hero undertakes the task of exposing the killer himself.

Gold miner Edd Denmeade loves Lucy Watson, the sister of the official mining claim recorder. Denmeade suspects Watson of killing his father, who after a poker game was shot by a gambler "who shuffles with one hand." The real murderer, Sam Spralls, has convinced Watson that he killed Denmeade and threatens to expose him unless Watson assigns him all the gold claims. Spralls assembles a band of killers to jump the claims when Watson complies. Eventually, Denmeade learns the identity of the killer when he sees Spralls shuffle a deck of cards. He forms a vigilante party and rids the community of Spralls and his gang.
