Der Fall der Gerti B. (2019)

The Viennese detective Gerti B. is already in a bad mood because of a conflict with her boss, when she is called to investigate the case of a coffin containing two corpses instead of one. Her prime suspect is a childhood friend, Franz, who runs the bordello where the victim worked. Meanwhile, a killer, Jonas (a former friend of both Franz and Gerti) has been engaged to dispose of Franz. The film is rightly subtitled; "A Story that could only happen in Vienna".
