A small sliver in the whirlpool of the Second World War, an American with Russian roots, Irene Cole, very young, almost a teenager, was left alone: separated from her family during the evacuation from Shanghai, she will courageously endure all the trials that befell her, living with one dream - again to see my mother and sisters someday. A ghostly dream, because their ship was sunk by the Japanese... And when a Japanese officer rescues her from a typhus barracks and sends her to her homeland, Irene - Rin - becomes the best friend of his legal wife, a woman she should have hated. A confusing labyrinth of relationships in a country with unusual customs... But when the girl finds out that her relatives have survived, she will have to make the most difficult decision in her life - who is her real family.
