One September morning, elderly Ruth Wesemann wakes to the sound of a parcel being delivered. Inside she finds a tattered little notebook and is met with a flood of memories. It's 1933 and Hitler is making his first speech as Chancellor of Germany. Her life and those of her friends are about to change beyond all recognition. Having dedicated themselves to resisting the Nazi's rise, they have become hunted outlaws. Fleeing the country, Ruth finds refuge in Bloomsbury, but inspired by her cousin Dora, they continue their dangerous resistance work. And then, one day, they face the chilling realisation that Hitler's reach extends much further than they had thought.
