Paris, 1919. Margot Rosenthal has arrived in France with her father, a German diplomat. She initially resents being trapped in the congested capital, where she is still considered the enemy. But as she contemplates returning to Berlin and a life she hardly knows anymore, she decides that being in Paris is not so bad after all. Bored and torn between duty and the desire to be free, Margot strikes up unlikely alliances: with Krysia, an accomplished musician with radical acquaintances and a secret to protect; and with Georg, a naval officer who gives Margot a job and a reason to question everything she thought she knew about where her true loyalties should lie.
