In a Balkan country mending from years of conflict, Natalia, a young doctor, arrives on a mission of mercy at an orphanage by the sea. By the time she and her lifelong friend Zóra begin to inoculate the children there, she feels age-old superstitions and secrets gathering everywhere around her. Secrets her outwardly cheerful hosts have chosen not to tell her. Secrets involving the strange family digging for something in the surrounding vineyards. Secrets hidden in the landscape itself. But Natalia is also confronting a private, hurtful mystery of her own: the inexplicable circumstances surrounding her beloved grandfather's recent death. After telling her grandmother that he was on his way to meet Natalia, he instead set off for a ramshackle settlement none of their family had ever heard of and died there alone. A famed physician, her grandfather must have known that he was too ill to travel. Why he left home becomes a riddle Natalia is compelled to unravel.
