In
Victorian England, everyone is trying to make new scientific discoveries, including such failures as the Duke of
Barset's attempt to create the first house in England illuminated by electricity (leading to its going up in flames), Sir Charles Dillworthy's
suspension bridge (which falls apart directly as
Queen Victoria cuts its inaugural ribbon) and, in
Germany, the disastrous recoil of Siegfried von Bulow's powerful new explosive (which is intended to require only a minute quantity). In the US, meanwhile, when
Phineas T. Barnum's "Greatest Show on Earth" burns to the ground, he heads to England with his star,
General Tom Thumb. Barnum and Thumb are invited to a scientific lecture by Von Bulow who proposes the idea of sending a projectile to the Moon using his powerful new explosive. Von Bulow is ridiculed, but Barnum thinks the idea has the potential to make him money. He sets about finding the financial backing in order to build a giant cannon to fire the projectile, carrying a reluctant Tom Thumb. The project attracts investment from all over the world; however, the spaceship designed by Sir Charles Dillworthy proves useless since it does not provide a means for returning to Earth. Barnum then meets an American
aeronaut, Gaylord Sullivan, who has run off with his girlfriend, Madelaine, on her wedding day to another man, the wealthy Frenchman Henri. Upon arriving in Wales and meeting Barnum, Gaylord claims that he has designed a projectile equipped with round-trip rockets. Henri offers to finance Gaylord's missile if he agrees to take Tom Thumb's place. Meanwhile, Dillworthy and his shady brother-in-law, Harry Washington-Smythe, who have already embezzled most of Barnum's funds, immediately plot to sabotage Gaylord's flight in order to win large wagers on the failure of the moonship expedition. When Madelaine discovers their plan, she is kidnapped and taken off to Angelica's Home for Wayward Girls. She escapes, however, and arrives back at the launching pad, located on a mountain in Wales, just as unconscious Gaylord is being removed from the sabotaged moonship. Dillworthy, Washington-Smythe, and a Russian spy, Bulgeroff (who rendered Gaylord unconscious), sneak into the spaceship to continue their sabotage. Bulgeroff pulls the takeoff lever, and the three men are sent soaring on a one-way trip thanks to Von Bulow explosive. They land in what is presumably barren wasteland to find inhabitants singing in Russian. The befuddled Washington-Smythe can only conclude that the Russians are already on the Moon; Washington-Smythe and Dillworthy find themselves as part of the
Burlak work brigade hauling barges under the
knout of the foreman (Bulgeroff) to the tune of
The Song of the Volga Boatmen. ==Main cast==
