Ted Dustin, an American inventor, seeks to win a prize of one million dollars
by being the first person to touch the moon with an object launched from Earth.
He devises a huge gun, which fires upon the surface of the moon. Shortly
thereafter, the moon fires back, and war breaks out between the planet and its
satellite. Using a videophone he invented, Ted hails communication with the
moon. A beautiful woman and her guards first reply, but their transmission is
cut off by warlike yellow aliens. Ted eventually heads to the moon in a
spacecraft of his own design, and meets the titular character, who turns out to
be the beautiful woman from the transmission, as well as a princess of one of
the two groups that inhabit the moon.
