White Thunder

During a feud between sheep-men and cattle ranchers, Sheriff Richards is murdered by a man with the ace of spades tattooed on his arm. Chick Richards returns from college upon learning of his father's death and impresses the townspeople as a foppish "dude" with no interest in avenging the murder. Soon after Chick's return, a mysterious, white-robed figure appears in town, fighting for the rights of the oppressed sheep-men. Black Morgan, the leader of the cattlemen, attacks Alice Norris, Chick's former sweetheart, and the White Rider appears, besting Morgan in a brutal fight. The mysterious stranger then removes his robe, reveals himself to be Chick, and arrests Morgan, who has the ace of spades tattooed on his arm. Afterward, Alice and Chick are married.
