The Lost Honor of Katharina Blum marks the directorial debut for actress
Margarethe von Trotta, who co-directed the film with her then-husband
Volker Schlöndorff. At a costume party, Katharina Blum (Angela Winkler) meets Ludwig Goetten (Jürgen Prochnow ) and spends the night with him. The next morning, he's gone and the police bust into her apartment looking for him with the belief that he is a dangerous terrorist. She is taken into police custody and interrogated by Kommissar Beizmenne (
Mario Adorf), who questions her about her every action. Meanwhile, sleazy reporter Werner Toetges (Dieter Laser) makes her story into a scandal in the papers by writing sensational stories about her personal life and portraying her as a criminal in photos. He exaggerates the testimonies of her ex-husband, neighbors, and even her elderly mother who is dying of cancer in an intensive care hospital. With the fear-induced public thinking she is a Communist and terrorist sympathizer, Katharina receives hate mail and personal threats until she is finally driven over the edge. ~ Andrea LeVasseur, All Movie Guide
