A saloon on the border between California and Nevada becomes the hideout for "Texas" Jack Slade's gang of rustlers. When the crooks start harassing the nearby ranchers, the town council calls the U.S. Cavalry for help. Two of their best men, Dan Wright and "Jack-Knife" Chandler are sent to wrangle the rustlers. But when they discover that Slade has assembled an army of thugs, Wright and Chandler must call in their fellow cavalrymen for an all-out war.
