Plot hole: The judge asks Jed Cooper if he would like to see what McCloud looks like, (McCloud is the killer who cheated him and murdered the rancher), as he is being hanged. Of course since Jed Cooper had previously purchased the cattle from McCloud, he knew what he looked like. (00:10:00 - 00:15:00)
Plot hole: On her first night alone on the McBain farm, Jill hears someone playing a harmonica out there in the dark. She blows out a candle (but there is still plenty of light in the room), grabs a gun, positions herself at the brightly lit window, and shoots when the sees tha harmonica player lighting a match. This behavior is way too foolish for a women depicted as street-smart as Jill. (00:55:30)
