London, 1939

As war breaks out in Europe, two families face their own conflicts. Two Quaker brothers, Paul and Charlie Lamb, sign a pledge of peace. Jewish crystallographer Mrs Morningstar sleeps restlessly, unable to bear the guilt of her work. And her daughter, Miriam, comes home with her stockings inside out but can't confess where she has been.

By the end of the war, they will each have to make impossible choices. Lines will be crossed, secrets will out, and lives will be lost.
