In the very darkest hour, who do you trust, who do you love, and who can be saved? It is 1943 - the height of the Second World War. With the men taken by the army, Berlin has become a city of women. And while her husband fights on the Eastern Front, Sigrid Schroeder is, for all intents and purposes, the model soldier's wife: she goes to work every day, does as much with her rations as she can, and dutifully cares for her meddling mother-in-law. But behind this facade is an entirely different Sigrid, a woman who dreams of her former Jewish lover, who is now lost in the chaos of the war.Sigrid's tedious existence is turned upside-down when she finds herself hiding a mother and her two young daughters: could they be her lover's family? Now she must make terrifying choices that could cost her everything.
