Oil is discovered on the ranch lands causing the dormant Remington-Randall feud to break out again. Lew Remington returns home to find himself embroiled in the struggle. The Randall faction is represented by Bob Randall, who is the unwitting tool of John Heydrick and his henchmen.

Beyond the Pecos features Rod Cameron in one of his early westerns that is a typical fast riding and fast shooting B-western, though there seems to be more plot here, a good buildup to the conflict. The villain is quite interesting, he doesn't like to be disturbed while he's playing his piano. Fuzzy knight is his usual comic self assisting the hero. He lugs around his boat! The finale is a slam bang finish!
