When sixteen year old Theo Drew meets Anna Levinsky, a Holocaust survivor, he is barely alive. Cosseting him in her home, Anna cares for Theo while he recovers from extreme emotional trauma in the wake of a family tragedy. Believing he may be responsible for the distressing events that occurred on a bleak, winter's afternoon in his family home, Theo finds solace in the story of Anna's life. Listening to her unfathomable existence, living under the Nazi regime in the ghetto of Theresienstadt, Theo realises that her improbable rescue may also be the key to his own salvation.
