Both Scotland Yard and an amateur American sleuth are tracking a master criminal known as The Frog. This moniker refers to the bulging-eyed mask worn by the evildoer, and is reflected by the frog icons painfully tatooed onto the forearms of his henchmen. The trail leads to the country manor of an enigmatic, steely-eyed nabob, whose repressed son has eyes for the artistes at the Lolita cabaret, and whose lovely daughter captures the fancy of both the American playboy and the villain himself.

Commander McLane and the crew of the fast space cruiser Orion patrol Earth's outposts and colonies in space and defend humanity from the alien 'Frogs'.

The movie reports the historical story of Schinderhannes, based on a play by Carl Zuckmayr. Johannes Bückler, this his real name, led a band of brigands in the Hunsrück mountains during Napoleonic times. (imdb)
