Paris, 1939: Young mothers Elise and Juliette become fast friends the day they meet in the beautiful Bois de Boulogne. Though there is a shadow of war creeping across Europe, neither woman suspects that their lives are about to irrevocably change. When Elise becomes a target of the German occupation, she entrusts Juliette with the most precious thing in her life --- her young daughter, playmate to Juliette’s own little girl. But nowhere is safe in war, not even a quiet little bookshop like Juliette’s Librairie des Rêves. When a bomb falls on their neighborhood, Juliette’s world is destroyed along with it. More than a year later, with the war finally ending, Elise returns to reunite with her daughter, only to find her friend’s bookstore reduced to rubble --- and Juliette nowhere to be found.
