1952, Paris. Nadia, a Red Diaper baby, has a sister, Polish parents, and at 15 is an active Communist. When cops beat her during an anti-American demonstration, she’s rescued by a “Match” photographer. As the friendship becomes a love affair and her slogans are tested by new knowledge and emotion, some of the Red youth want to expel her. When she goes with Stéphane to a seaside photo shoot, her father goes to the police. Stéphane faces charges, so leaving to cover the war in Indochina looks appealing. In a parallel story, Nadia’s mother meets again her prewar lover, released from Siberia, who challenges the French Reds with very real scars and word of Stalin’s anti-Semitism.
