Team DANKAI are set to compete in the Paris-Dakar Rally, an off-road endurance race spanning thousands of miles and multiple continents. Prior to the event, DANKAI leader Mizuki is ordered by their sponsor to add popular celebrity Ryuichi Yoshii to the roster for publicity. This exacerbates DANKAI's resentments and baggage. Needing a steady hand to mediate dispute and navigate their support vehicle, Mizuki recruits legendary retired mechanic/driver Eiji Honma to the team. Soon Honma discovers his ex-wife Kei is also participating in the rally, alongside her current husband, the bullfighter Antonio Vázquez. Honma's truck also comes to include stowaway passenger Yuko Takei, Yoshii's pop star girlfriend who is trying to salvage their relationship.
