Approaching 80, frail and alone, a remarkable man makes the journey from his sheltered home in England to Berlin to meet his granddaughter.
As she sets out to unravel the truth about what really happened to her sister, Nina comes face-to-face with inner demons she believed long since banished and discovers that her sister's past and that of the once-divided city are intertwined in unimaginable ways.
It's April 1939 and, with their lives in Berlin and Vienna under threat, Esther and Kitty – two very different women – are forced to make the same brutal choice. Flee Europe, or face the ghetto, incarceration, death.
