The Hiyama brothers work for a racing team. Naozumi's reckless driving causes friction with his brother Atsuhiro. An amnesiac man named Endo suddenly believes he is Naozumi, leading to more friction.

At the SCRS (Seiko Cup Rally Series), talented young drivers hope to advance to the WRC (World Rally Championship). Atsuhiro Hiyama (Masahiro Higashide) is the chief mechanic and an engineer at Supika Racing Factory. He is well regarded by his peers. His younger brother is Naozumi (Mackenyu Arata). He is an extremely gifted driver for Supika Racing Factory, but he is also a troublemaker. They continually argue because of Naozumi's reckless racing style. One day, Hikaru Endo (Aoi Morikawa) becomes his manager.—AsianWiki
