Victor Frankenstein (puzzlingly called "Count" Frankenstein here) discovers neanderthals living in a cave near his castle. When one of them is injured, Frankenstein revives him as his newest cut-n-paste creation, a giant fuzzy haired beast called "Goliath". He even has help from an servant named "Ygor" Meanwhile, Frankenstein's perverted dwarf assistant "Genz" has befriended an older, mute, cave dweller; a hairy wild-man named "Ook" and uses him to procure young lovelies for Genz to fondle, as well as to take revenge on his unsympathetic master. Meanwhile, Frankenstein is courting his daughter's best friend who is young enough to be his granddaughter, and the village people are becoming suspicious about the goings on at Castle Frankenstein (But, don't they always?) and also want to know who is lurking in the neanderthal's cave.
