Jiro Kanzaki is an F3000 driver blessed with acute sensitivity and breathtaking driving techniques. He's a daredevil who feels no fear driving at speeds that even top racers dare not attempt. But unexpected trouble forces this racer to leave his team and return to Japan for the first time in years. Until he finds a new job as a racer, Jiro decides to stay with his family. What awaits Jiro there is his hardheaded father, his nagging sister, the 12 children of the foster home his father runs, a snobbish male teacher, and a stubborn female teacher who likes to daydream about her life. Jiro's return home brings a breath of fresh air that influences the people around him. However, he is still unaware that he too will eventually be influenced to change the way he thinks and lives.
