Legendary lawman Bat Masterson (Randolph Scott) is called to rural Kansas to defend farmers from ruthless cattlemen. Joining Masterson in his efforts to clean up a lawless town are a couple of locals: Masterson's old chum Billy Burn and landowner Allen Harper (Robert Ryan). But ranch owner Logan Maury proves to be a more than formidable opponent. He'll stop at nothing, including murder, to turn the farmers' fields into grazing grounds for his cattle.
