Robin Hood of the Pecos was set immediately after the Civil War, when most of Texas was under the thumb of corrupt northern politicians. Alleviating things somewhat is the presence of a mysterious masked night rider, inclined to rob from the rich and give to the poor. Believe it or not, this latter-day Robin Hood is not played by star Roy Rogers, but by his grizzled sidekick Gabby Hayes! No matter: the plot is resolved when Rogers swings into action against crypto-fascistic local adjutant Cy Kendall. Repeating her "Calamity Jane" characterization from Young Bill Hickok, Sally Payne plays a gun-wielding hoyden, while the more sedate heroine is enacted by Marjorie Reynolds.
