Although ostensibly the grand-son of the legendary hero, Clayton Moore's Ken Mason is little more than a cowboy in a black mask in this 12 chapter Republic serial. Mason, the head of the telegraph line work crew, assumes his ancestor's trade-mark mask (but not whip) in order to prevent a local czar (Roy Barcroft) from sabotaging the burgeoning telegraph line. Pamela Blake, a brunette starlet formerly known as Adele Pearce, played Mason's imperiled girlfriend, and the serial also benefitted from the usual competent work of Republic's great stunt-performers, including Dale van Sickel, Tom Steele, Eddie Parker, and Joe Yrigoyen.
