Watch on Soap2day. Johnny Mack Brown stars in this above-average B-Western from Monogram, penned under the pseudonym of Jess Bowers by veteran genre specialist Adele Buffington. Mack Brown plays Johnny Murdoch, a drifter arriving in Gold Flats in search of his prospector father. From old-timer Dusty Hanover (Raymond Hatton), Johnny learns that Old Man Murdoch was murdered for his claim by Rex Hillman (Holly Bane), a hireling of Carter Morgan (Bill Kennedy).
