A remake of the 1952 western "High Noon," about lawman Will Kane, who promises his young bride, Amy, that he will leave his dangerous career to start a ranch. Just as the newlyweds are about to leave town, word comes that a man whom Kane sent to prison years earlier, is coming to town on the noon train seeking vengeance. Kane attempts to rally the town to fight the gunman, but not even his former deputy, Harvey, is willing to help. Harvey's cowardice infuriates his girlfriend, Helen, whose romantic past with both Kane and with the arriving gunman convinces her to pack up and leave town. As the dreaded noon hour approaches, Kane realizes he must stand alone against killer, despite his promise to his wife.
