Synopsis by Hans J. Wollstein
Veteran cowboy star Harry Carey played a ranger in this silent Western melodrama directed for Universal by action specialist B. Reeves Eason. Ranger Job McCoy, nicknamed "Blue Streak," comes to the aid of prospector Howard Marlowe (Charles Arling) and his blond daughter Eileen (Lila Leslie), whose valuable mine is under siege from a dastardly villain (the nasty-looking Charles LeMoyne). The director's six-year-old son, Breezy Eason, Jr. played Eileen's kid brother. Billed as Universal's Littlest Cowboy," the tyke would perish in a tragic on-set accident during the making of yet another Carey Western, The Fox (1921). Eason, Sr., who would later excel as a director of action serials, had taken over the Carey Westerns from John Ford.
