Watch on 123Movies. Documentary about Berlin's "Salon Kitty," a brothel that was systematically used by the Nazis for espionage. The owner's daughter took over the premises in 1953 and gradually converted them into an artists' guesthouse. In the early 1990s, her grandson tried unsuccessfully to set up a guitar school, and since then the guesthouse has mainly accommodated asylum seekers. Rosa von Praunheim traces the history of the house in conversation with prominent contemporary witnesses.
