Der Vulkan (1999)

Berlin 1937. In Germany, the fascists inexorably come to power. Marion Von Kammer watches helplessly as the Nazis destroy the small theater in which she performs forbidden songs. Disgusted by what has become of Berlin, Marion flees to Zurich with her sister Tilly and their mother. Tilly lives this exile in lovelorn despair, having left her lover there. Exiled again in Paris, Marion meets Martin. Together they broadcast anti-fascist propaganda on a German underground radio station and Marion sings her forbidden songs in a small Parisian bar. But fascist ideology spreads like an octopus.
