Marshal Gary Cooper is about to turn in his badge and leave Hadleyville forever with his Quaker bride Grace Kelly on his arm… But Frank Miller, a man he sent to prison, is due back in town on the high noon train. With the Miller gang bent on revenge Cooper has about an hour to gather deputies, but everyone in town turns him down. Even his pacifist wife seems ready to desert him. Tex Ritter’s "Do Not Forsake Me, O My Darling" resonates as the clock relentlessly advances toward high noon.
