In 1944 Nazi-occupied France, the young Marguerite Duras (Mélanie Thierry) is a talented writer and an active Resistance member with her husband Robert Antelme (Emmanuel Bourdieu). When he is deported by the Gestapo, she dives into a desperate struggle to get him back. She develops a chilling relationship with the detective Rabier (Benoît Magimel), and takes terrible risks to save Robert. Does Rabier he really want to help, or is he trying to dig up information about the anti-Nazi underground? Then comes the end of the war and the return of surviving camp victims, a long and silent agony after the chaos of the liberation of Paris. But she continues to wait, bound to the torment of absence even beyond hope and love.
