i would recommend the canon of films by Margarethe von Trotta, part of the german new wave which included hertzog, fassbinder, Schlöndorff. etc. Her ouvre spans the history of post war germany.
The German Sisters, 1981 (Badder Meinhof backgound)
Rosenstrasse (2003 ( women with jewish husbands resistance in berlin to the nazis)
The Lost Honour of Katharina Blum (Die verlorene Ehre der Katharina Blum, 1975). The latter is a story about a young woman who has a casual affair with a man she's just met – a man she later discovers is a terrorist.
Rosa Luxemburg (1986)
The Promise (Das Versprechen, 1994)
