Berlin, 1933. Warning bells ring across Europe as Hitler comes to power.
Clara Vine is young and ambitious, and determined to succeed as an actress. A chance meeting at a party in London leads her to Berlin, to the famous Ufa studios and, unwittingly, into an uneasy circle of Nazi wives, among them Magda Goebbels.
Then Clara meets Leo Quinn who is undercover, working for British intelligence. Leo sees in Clara the perfect recruit to spy on her new acquaintances, using her acting skills to win their confidence.
But when Magda Goebbels reveals to Clara a dramatic secret and entrusts her with an extraordinary mission, Clara feels threatened, compromised and desperately caught between duty and love.
