Spoilers of the Range (1939)

Hero Jeff Strong (Starrett) comes to the rescue of a group of victimized ranchers. The villains are a gang of crooked gamblers, who demand a valuable dam as payment for a $50,000 debt. The ranchers hope to earn the money by getting their cattle to market on time, but head bad guy Cash Fenton (Kenneth MacDonald) and his flunkey Lobo (Dick Curtis) intend to prevent this.
