 Because town cut-throat Phil Randall (Jack Ingram) wants the ranch owned by "Pop" McGee (Steve Clark) on which is located a valuable silver deposit, he frames McGee on a cattle rustling charge, and the old man is sentenced to hang. "Boots" Annie (Sarah Padden)is determined to save him, so she sends for U. S. Marshals Nevada Jack McKenzie (Johnny Mack Brown) and Sandu Hopkins (Raymond Hatton), who rescue McGee from jail on the eve of his hanging. They then set out to gather the evidence to clear McGee and convict the real villains. Swede Larson (Art Fowler) and Sheriff Jed Hawkins (Hugh Prosser), working with Randall, conspire to get the marshals out of the way and hire the Dawsons (Lynton Brent and Stanley Price) to do the job. The job backfires and the first Dawson is shot, but before the dies, he talks and enables Nevada and Sandy to nake arrests and clear McGee of any charges.
