Lockvogel der Nacht (1959)

The unscrupulous Klaus Petzold has developed a very special business model: with his company, which outwardly presents itself as a normal detective agency, he is the logical consequence and at the same time the counterpoint to the institution of marriage agencies. While some people work to bring two people together, Petzold's Frankfurt establishment offers a service designed to make it easier for clients to get a divorce.
