From dusk until dawn, street racers converge on a Tokyo highway—the Wangan Route—seeking only one thing: speed. Among them, a newcomer catches the eye of the route's veterans after buying a Nissan Fairlady Z, a car infamously nicknamed The Devil Z. This newcomer disregards the warnings of Eriko Asakura, who lost her brother, Akio, in an accident involving that same vehicle. The Devil Z's new owner, who coincidentally shares the exact same name as Eriko's brother, becomes entranced by the car's mysterious power—even after crashing twice. Now a high school dropout working to pay for his car repairs, Akio befriends regular street racers of the area: the legendary owner of the Porsche 911 Turbo, a car known on the streets as "Blackbird;" the genius surgeon Tatsuya Shima; and Reina Akikawa, who works as a model by day and displays unparalleled skill in her Nissan Skyline GT-R by night. Thanks to these connections, Akio manages to find the retired designer of The Devil Z's engine, a solitary man named Jun Kitami. Following his meeting with Akio, Jun resumes building overpowered yet dangerous engines. Meanwhile, the racers of the Wangan Route are caught in a desperate race against The Devil Z with no clear end in sight.
