Okinawa, Japan, World War II. Momoko Akiyama is the daughter of an intellectual couple. Her only worries are: the political dissidents who arrive at the house by night and leave by night; her brother's escapades on early Wednesday mornings and bullying at school. Jun Kobayashi, a grave-digger's daughter, is cripplingly shy and can hardly speak a word without stammering. But everything in life they took for granted will soon change for ever. With a conscription letter. With a lie. With a betrayal. With a man hidden in chest. With the war knocking at their doors.
