In Berlin in 1961, an American soldier and a German engineer join forces to build a tunnel under the Berlin Wall in order to smuggle out refugees, including the soldier's East German girlfriend.

In 1939, Charlotte Salomon leaves Berlin to seek refuge at her grandparents' villa in the south of France. A little later, war breaks out, and Charlotte must, besides forgetting all she left behind, deal with her grandmother's depression, and her mother's suicide. To fight despair, Charlotte starts to paint, producing over one thousand images. "Is my life real, or is it theater?" This is the title she gives her body of work, which highlights her former life in Berlin. She finds herself though her art, but in 1943 is deported to Germany and Auschwitz.
