When Mr. Böhm learns that he can make money by claiming to be a murderer, he pretends to be a woman-killer. His old school friend Lehmann then takes him to his agent Mr. Marojan. While the "factual report" is in full swing, the police discover the truth, namely that Böhm is not a murderer at all. So as not to disappoint the magazines, Böhm, Lehmann and agent Marojan come up with a perfidious plan: Böhm is actually to murder women. A victim is soon found, but "woman killer" Böhm makes a fatal mistake..."
