This film’s story occurs sometime after Fast & Furious 6 with a scene that was later made concurrent with events in Furious 7.
After totaling his car in an illegal street race, Sean Boswell (Lucas Black) is sent to live in Tokyo, Japan, with his father, a U.S. Navy officer, in order to avoid juvie or even jail.
While in school, he befriends Twinkie (Bow Wow), a “military brat” who introduces him to the world of drift racing in Japan. Though forbidden to drive, he decides to race against Takashi (Brian Tee) aka D.K. (Drift King) who has ties to the Yakuza. He borrows a Nissan Silvia from Han Seoul-Oh (Sung Kang), now a business partner to Takashi, and loses, totaling the car because of his lack of knowledge of drifting – racing that involves dangerous hairpin turns. To repay his debt for the car he destroyed, Sean must work for Han. Later on, Han becomes friends with Sean and teaches the young racer how to drift.
Takashi’s uncle Kamata (Sonny Chiba) (the head of the Yakuza) reprimands Takashi for allowing Han to steal from him. Takashi confronts Han, Sean and Neela (Nathalie Kelley), and in doing so, they flee. During the chase, Han is killed in a car accident as his Veilside Mazda RX-7 catches on fire. Takashi, Sean, and his father become involved in an armed standoff which is resolved by Neela agreeing to leave with Takashi. Twinkie gives his money to Sean to replace the money Han stole, which Sean then returns to Kamata.
Sean proposes a race against Takashi to determine who must leave Tokyo. Sean and Han’s friends then build a Ford Mustang ’67, with an inline-6 engine and other parts salvaged from Han’s Nissan Silvia that Sean had wrecked. Sean wins the race. Later, Sean is challenged by Dominic.
