Berlin, 1932. Germany’s fragile democracy is fracturing, its ideals cracking like thin glass as political violence and paranoia seep into the streets. In the midst of this tension, Rudi, a young Foreign Ministry official, meets Sara, an unpredictable, morally fierce Jewish woman whose connection with him is immediate and combustible. By 1943, the Germany they knew has vanished, and Rudi works at the center of Nazi power, performing his duties by day and passing intelligence to the Allies by night --- until Sara’s unexpected return threatens to unravel the life he has carefully constructed to survive.
