A Child in Berlin is the true story of a mother, a daughter, and their courage in the face of Nazi terror. Käthe is a mother who must choose between her dreams as a rising star in the opera and her conscience. She discovers the truth about her Jewish friends around the time she attends a dinner party presided by Adolf Hitler himself. She realizes she cannot remain among Nazi society and makes the gut-wrenching choice to leave the opera. To support herself and young Heidi, she joins Berlin's black-market network and ends up dealing with more than just food. As others evacuate the capital, Käthe harbors a secret that anchors them in the epicenter of danger.

While Käthe becomes ever more preoccupied with survival, Heidi and a roving pack of friends make mischief in Berlin's rubble. The war devolves, and Heidi braves hunger, cold, and feelings of abandonment as shuttles between Berlin and the Polish countryside. Heidi's ultimate test comes when she must survive alone in a bombed-out apartment during the final weeks of World War II. Her moxie shows how children are capable of far more than adults realize.
