 Invisible aliens in a tiny flying saucer come to Earth looking for heroin. They land on top of a New York apartment inhabited by a drug dealer and her female, androgynous, bisexual nymphomaniac lover, a fashion model. The aliens soon find the human pheromones created in the brain during orgasm preferable to heroin, and the model s casual sex partners begin to disappear. This increasingly bizarre scenario is observed by a lonely woman in the building across the street, a German scientist who is following the aliens, and an equally androgynous, drug-addicted male model. (Both models are played by Anne Carlisle, in a dual role.) Darkly funny and thoroughly weird.
