In what appears to be a rip-off of Frankenstein, three women, one English, one Austrian and one Mexican, come to a house where an old woman wants to take their brains. That's about as intelligent as the plot gets. Because every other aspect of "Monstrosity" is so idiotic, you start wishing that a big ugly monster would pop out and demolish the whole house. This movie was once shown on "Mystery Science Theater 3000", which is exactly where it belongs, especially since Mike, Servo and Crow have so much fun mocking the English woman's phony accent.
Oh, and the alternate title is "The Atomic Brain", but no one's brain is actually atomic!
