Ranger Courage

Bull, the leader of a gang, disguises his men as Indians and leads them in an attack against a wealthy wagon train. A young boy, Buzzy, sneaks away, and summons the rangers. The arrival of the rangers disperses Bull's gang. Buzzy introduces his older sister, Alice, to Bob, a ranger, who has become his idol. Bob collects evidence that contradicts the claim of an Indian attack, and he goes undercover as a prospector. When Bob goes to the saloon in Hopi, he meets Bull and some of his men.
