After losing her young daughter Kanako in a traffic accident on her first day of school, homemaker Yoko makes the desperate decision to go and see her in the afterworld by committing suicide, only for it to fail, leaving her with a near-death experience. Since that day, Yoko starts telling her husband Nobuki that Kanako is back in their home, although she remains invisible to Nobuki. After a while, Kanako’s presence slips away from Yoko, but Kanako’s dog leads her to Masami, a pregnant teenager who is about to become a single mother. Believing that Masami carries her daughter’s reincarnation and seeing a sign when Natsuki, the baby, is born, Yoko helps Masami look after her, waiting for the child to become old enough to speak. Yoko had two questions that she must ask her – whether she remembers Yoko from her previous life… and whether she wants to return to Yoko.
