Strange things are going on in the sleepy little town of Stadtlohn. A doctor at the local hospital is experimenting with his patients to turn them into will-less "exhibitionist killers". Unfortunately, the first leather coat creature manages to escape to his family. But strangely enough, the exposure results in his immediate death. The sister of the noodle wielder is not at all pleased about this and wants to inform the police about the mad doctor. In the meantime, he has created a whole army of perverted murderers and sends them out to destroy the witnesses. A bloody butchery marathon takes its course.
