Playboy Red Mitchell suffers from chromosome malformation X+YY, a dangerous deformity of the libido. At night, driven by inner turmoil, he roams the streets of the city and murders women. Preferably young, pretty girls who become his victims after he has seen them naked in his imagination with his X-ray vision and then undresses them in real life to kill them. But he soon leaves traces behind, and a cunning detective who suspects his chromosomal drive is on Mitchell's trail...

The film features several horse trainers and other track workers talking about their roles at the track, always eventually interrupted by an older man who claims to be the true authority, and demands that they be thrown out. One recurring young man, the first to appear, claims that he protects the horses from enthusiastic racing fans. He does not appear to be employed by the track, but seems to provide his services voluntarily. His protection from "fanatics" gives the film its title. The film is shot in a documentary style, but the sheer implausibility of the dialogue leaves the exact nature of the film ambiguous.
