First Lieutenant Shun'ichi Maki of the Japan Air Self-Defense Force is a prestigious F-15 Eagle jet pilot (or "driver" as he is called in the film). A lifelong fan of flying since he was a child, being a pilot is his ultimate dream. Unfortunately, his duties distance himself from his wife, Yoko, who always ends up being neglected, and his son, Tsugumu, who has a congenital blood disease and has a high risk of dying at a young age.Maki decides to quit the Air Force to devote more time to his family and to spend whatever is left for his son. He takes a part-time job as a commercial tour guide run by a kindly group of people who allow him time to work and to also take care of his family.
