It presents a richly detailed portrait of life in Berlin under the Nazis and tells the sweeping saga of one working-class couple who decides to take a stand when their only son is killed at the front. With nothing but their grief and each other against the awesome power of the Reich, they launch a simple, clandestine resistance campaign that soon has an enraged Gestapo on their trail, and a world of terrified neighbors and cynical snitches ready to turn them in.
