A man is rescued dead from the Elbe. The autopsy shows he was electrocuted in his bathtub. Chief Inspector Jan Casstorff suspects a planned murder. He and his team find out that the dead man is the unscrupulous entrepreneur Heinrich Kehl, who in the 1980s rose as a porn producer and then as a real estate speculator just as quickly as he later fell. Kehl lived in Hamburg in an apartment building that he had officially signed over to his sister, although he was actually the landlord himself.
