Racketeers never rest -- a lesson journalist turned masked avenger Britt Reid (Warren Hull) learns when he dares to head off to the Hawaiian islands for a richly deserved holiday in this 15-part sequel to Universal's 1940 serial. With loyal valet Kato (Keye Luke) at the Hornet's side, he weathers a plane crash, a laboratory explosion and more as he tries to crack a far-reaching criminal organization run by a crook named Crogan (Pierre Watkin).
