Germany, 1926. When Richard and Paula meet in bustling, cosmopolitan Hamburg, everything feels possible. They fall in love, marry and are soon blessed with twins, a beautiful boy and girl. When Richard qualifies as a psychiatrist, life ahead looks bright. Their only sadness is that their son, Georg, was born deaf, although with his family to protect him they’re sure he’ll be okay. But happiness turns to horror when the Nazis seize power and begin forcing doctors to euthanise anyone the regime deems imperfect. Suddenly, Richard is falsifying medical records to save his patients – and hiding Georg, whose deafness now makes him a target for the authorities. With his family plunged into darkness and his son’s life in his hands, can Richard find the strength he needs to keep his family together and evade the world’s most merciless regime?
