Francois, a solitary, imaginative child, invents for himself a brother as well as the story of his parents’ past. But on his fifteenth birthday, he discovers a dark family secret that ties his family’s history to the Holocaust and shatters his illusions forever. Before the war, his father, Maxime, was married to Hannah when he fell madly in love with Francois’s mother, Tania. As a young Jewish couple living in Nazi-occupied France, Maxime and Tania were compelled to make difficult choices to survive the war while Hannah would make a decision that would change her life and that of her family forever.
