Two escaped prisoners hide out in a rocket built by a scientist. The scientist flies the rocket (with the 2 prisoners, his assistant and the assistant's fiancee) to the Moon. They disocver a dying all-female society, and learn that the scientist (who died during the trip) was actually the last surviving Moon man who had been sent to Earth in an effort to save the Moon civilization.
Two versions of this Rifftrax were produced - the first features Mike Nelson and special guest riffer Fred Willard. The second features Mike, Kevin and Bill, using mostly the same jokes. Purchasers could also choose between a restored black and white version and a colorized version.
