Two kids, fourteen-year-old Eriko and her thirteen-year-old brother Daigo, suddenly find themselves trapped in a parallel universe. Most things are the same as in their own world, but their parents are missing from home and are only contactable when using one particular phonecard. Based on a novel by the Akutagawa Prize-winning Fujino Chiya, and directed by the writer of Nakata Hideo's Dark Water.
