Judith Fontaine is looking for her sister Joanie, who has disappeared into the hippie community of Venice, California. It turns out that Joanie has become fallen victim to Groton, an ax-wielding homicidal maniac under the employ of Dr. Durea, the last living descendant of the Frankenstein family and is now both running a house of horrors on the beach's boardwalk and performing experiments on Gorton's victims in his basement laboratory.

Amir, the benevolent ruler of Kalid, is dying, but there is hope. Freshly deceased, he is flown to the United States where Dr. Trenton transplants his brain into the body of a simpleton in a classic "assistant got the wrong kind of body" plot line. Dr. Trenton has a few nefarious plot twists of his own in mind, and then there's the thing with the dwarf and the women chained in the basement. It's up to Amir's friend Bob and wife Tracey to try and salvage this tale.
