A sex maniac (bald and wearing white shoes) kills young women by penetrating them with various car parts. After each crime, he calls Commissioner Jason, head of a special police unit. The "anti-sex brigade" consists of three impassive detectives, whose main activity consists of collecting the variously undressed bodies with a few crude comments, or even touching them inappropriately. However, one of the victims has survived: the commissioner decides to use her as bait.
