Plot
Mad scientist Dr. Durea, the last descendant of the original Dr. Frankenstein, takes to murdering young girls for experimentation in hopes of perfecting a blood serum of his own creation with help from his mute, simple-minded assistant Groton. Durea hopes the serum will heal his paralyzed legs and cure Groton of his condition. Count Dracula comes to the scientist, promising to help him revive the Frankenstein Monster (which he has exhumed from its secret grave in nearby Oakmoor Cemetery) in return for Durea's serum, which he hopes will grant him the ability to go out in the sunlight, thus making him invincible.
As a cover, the duo works out of a secret laboratory hidden behind the Creature Emporium, a haunted house exhibit and a throwback to the old sideshow days located on the boardwalk amusement park in Venice, California. They bring the Monster back to life, and Durea sends him and Dracula out to exact revenge on the man who both discredited him and crippled him in a laboratory fire, Dr. Beaumont. Las Vegas showgirl Judith Fontaine has also previously arrived, looking for her missing sister Joanie who was last seen hanging out with a group of hippies led by Strange. Judith has gotten no satisfaction from Sgt. Martin. She says she is going to investigate on her own and does so, attracting the attention of biker Rico and his gang. Rico slips her some LSD at a dive bar with the bartender's help and Judith, while on a trip due to the drug, is taken by Strange and his girlfriend Samantha, who have just finished attending a protest, to the home of aging fellow hippie Mike Howard who agrees to help her find Joanie. Judith, Mike, Samantha, and Strange go to the Creature Emporium (which Joanie had been known to go to many times), and Judith shows Durea a picture of Joanie, asking her if he has seen her, but he says that he has not.
