1950 film by Thomas Carr

Columbia's 34th serial production starring Buster Crabbe, the Serial King himself

A newsman helps a Brazilian singer get her brother out of trouble in New York.

Detective Chick Carter (Lyle Talbot)finds himself on his most exciting case when Sherry Martin (Julie Gibson), a singer at the Century Club, reports the robbery of the famous Blue Diamond, owned by Joe Carney (Charles King), the owner of the nightclub.

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.

A shop owner tries to interest his heirs in the family business.

A young woman's murder sheds light on a crooked talent agency.

The East Side boxing champion Muggs answers a challenge to a fight against the West Side champ but just before the match he is kidnapped. His friend Danny Lyons takes his place and wins the fight, only to have Mugs believe that Danny was responsible for his kidnapping.

Susan Hart, assistant to private detective Russ Ashton, is given a camera concealed in a hat box and assigned to take a picture of a woman. A gun is accidentally hidden in the box and the woman is killed. Susan is charged with murder, but Russ and his less-than-useful associate, Harvard, get on the case.
