A range war is coming to the valley. Ambitious land baron Lew Wilkison (Edward G. Robinson) and his hired guns from the Anchor Ranch have been driving other farmers off their land. Now they've gunned down the local sheriff and are looking to own the entire valley. Civil War veteran Captain John Parrish (Glenn Ford) doesn't want any trouble. He'd be happy to sell out to Wilkison and return back east. But when Wilkison's men kill one of his ranch hands, Parrish realises he has to stand his ground - and look to his guns.
