Nina Hoss stars in this adaptation of a novel by Klaus Mann as Marion von Kammer, a singer who leaves Germany for Zurich as the Nazis rise to power. However, she finds life in Switzerland dull and suffocating, so she journeys to Paris, where she works at a pirate radio station broadcasting anti-fascist messages. She becomes friendly with a group of fellow Germans living in the city of lights, including nightclub owner Mother Schwalbe; Professor Abel, the unofficial leader of the group; Martin Korella, a dissatisfied young author; and Kikjou, Martin's lover.
