On an island somewhere in the Caribbean a professor is experimenting with mankind. Meanwhile, The Red Lips are moonlighting on a striptease world tour, but as soon as they hit the stage, the girls are up to their pasties in stiffs, Satanists and Sapphic sadists, all after the professor's secret formula for human clones!
"Red Lips" are two female detectives trying to find missing models and dancers. A pop artist called Klaus Thriller and his werewolf-like assistant, Morpho, are the main suspects for the murderers.
Segundo López, a mature and very humble man who has arrived in Madrid from Cáceres, his homeland, meets Francisca, with whom he falls in love, and El Chirri, a roguish street urchin with whom he will have adventures all over the huge and hostile city.
