Tom Evans (Jon Dawson) has trail-driven his heard to Yucca City, where he intends to sell the heard to Ben Crowley (Harry Woods). Crowley is the town big shot who owns most everything of value in the town. The night before driving the cattle into town to make the final sale, Evans gets caught up in a crooked card game hosted by Crowley. During the game a U.S. Marshal, "Nevada Jack" McKensey (Johnny Mack Brown) who is working undercover, manages to obtain one of the fixed deck of cards. While Evans is engaged in the game Crowley takes his gang, rustles the cattle, and kills Evans' cowhands. When Evans learns his men have been shot, and his cattle stolen, he rushes out of the saloon, only to be shot in the back by one of Crowley's thugs. McKensey rescues Evans and shutters him with the local blacksmith Jeff Lewis (Sam Flint) and his daughters Mary. They send for U.S. Marshall Sandy Hopkins, Evans' uncle, and hatch a plan to make things right. Deception and gunfire ensue, and the good guys go for the win.
