"Terrifying monsters from a lost age!", promises the movie's ads from its original release in 1959. One can only assume they refer to John Agar, B-movie veteran and star of this immensely silly but moderately entertaining sci-fi/horror flick of yesteryear.

Agar, as archaeologist Dr. Roger Bentley and Hugh Beaumont (that's right, Ward from Leave It To Beaver) as Dr. Jud Bellamin drag Etienne LaFarge into what is apparently one of the world's many randomly positioned hidden underground civilizations, where they come upon a race of albinos who have enslaved horrible mole people. Apparently these mole people are only tangentially related to the story and, to the best of my understanding, reside in shallow pits of gravel in otherwise sturdy terrain and feed upon non-albino passers-by. Just like real albinos, the people of this race of english-speaking subterranean Brits are horribly afraid of any sort of light, and burn instantly to their off-screen deaths whenever they come into contact with natural sunlight. They are ruled by a king sporting a giant hood ornament for a hat, who is advised, of course, by Alfred the Butler (Alan Napier).

The esteemed Doctor Roger Bentley apparently then falls in love with one of the pale people, and after a bit of philosophical masturbation on the part of Bentley they decide to incite a mole-person riot, guided of course by rational thinking and the complex and deeply philosophical notion that slavery is bad. The resulting chaos destroys the ancient underground civilization, and somewhere along the line Bentley's love interest, Adad, gets squished by a falling pillar. The end.

I have also come across the information that "LaFarge" would translate into french as "the load". This would explain everyone on MST3k referring to LaFarge mockingly as a deadweight through the course of the flick (that is, up until he becomes a literal deadweight).

Also not to be confused with the molé people.
