In this intriguing film adaptation, siblings Eriko, aged fourteen, and her thirteen-year-old brother Daigo unexpectedly become ensnared in an alternate reality. While this universe mirrors their own in many ways, their parents are conspicuously absent from their home and can only be reached through a specific phone card. The story is drawn from a novel by Fujino Chiya, a recipient of the prestigious Akutagawa Prize, and is brought to life by the director who penned Nakata Hideo’s “Dark Water.”
