Synopsis:
While on a European cruise ship, Robby Reed overhears a coded radio message sent by agents of Thunderbolt. Robby becomes the super-hero Baron Buzz-Saw and tries to stop the criminal organization from stealing a construction machine known as Whrrr.

Robby fails to prevent the theft, but he continues to track them as another hero, Don Jaun. He locates the crooks, disguised as gypsies, but the Spanish women nearby attack him. Robby changes to another hero, Sphinx-Man and follows the gang to their secret base. Robby vanquishes the crooks, then notifies authorities to tell them where the Thunderbolt base is located.
