Twelve-year-old Koichi, who has been separated from his brother Ryunosuke due to his parents' divorce, hears a rumor that the new bullet trains will precipitate a wish-granting miracle when they pass each other at top speed.

Liang is a four-year-old little rebel, possessed of a pair of luminous eyes and a precociously indomitable will. His father deposits him at a well-appointed residential kindergarten in post-1949 Beijing, since his parents are often away. Life at the kindergarten appears rich and colourful, made up of a variety of cheerfully sunny rituals and games meant to train these children to be good members of society.
