The summer of a man's childhood recollections lives on. He has made contact with the ghost of a young woman from the World War II era while still on the verge of becoming a man. She and the ghosts of other young females from that era continue their journeys with their connected companions, learning more about each other and traveling across time via their mysterious connection. While he fights to see his infatuation on her blossom, his friend—a female his age who is pretending to be a boy—seeks his attention as well.
