Taking place in the Gunma prefecture in Japan, the film concerns a young tofu-delivery driver named Takumi Fujiwara. He has incredible skill in taking on the hairpin curves of Mt. Akina (Mt. Haruna in real-life). The film chronicles his evolution from an uninterested delivery boy into a hardened touge racer.
Takumi drives his father's (Bunta) Toyota Sprinter Trueno GT-APEX (AE86). It is seemingly unmodified but is perfectly suited for the downhill corners of Mt. Akina and gains the attention of local street racers all across the prefecture. Some ultimately challenge Takumi to battles on Akina's downhill. Ryousuke Takahashi, a driver of the Mazda RX-7 (FC3S) helps out Takumi along the way by giving him advice. While following the path of a street racer, Takumi must deal with his alcoholic father and his girlfriend who secretly engages in compensated dating.
