Rokuo Kazuki (Gitan Otsuru) is challenging to break the fastest time record to go around 7 tollways around Tokyo and Yokohama that stretches 13.9 km. Setting the record of breaking 5 minutes 13 seconds not only requires skill, but also luck. Failing to break the record, Rokuo gives up. Rokuo's girlfriend Yoshiko (Yumiko Okayasu) challenges the record. There's another confident street racer Takashi (Koji Matoba) also vying for the record.
