After totaling his car in an illegal street race, Sean Boswell is sent to live with his father, who is stationed as a U.S. Navy officer in Tokyo, Japan, to avoid juvy or even jail. While in school, he befriends Twinkie, a "military brat", who introduces him to the world of racing in Japan. Though forbidden to drive, he decides to race against Takashi, the Drift King, who has ties to the yakuza. He borrows a car from Han, 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, a yakuza head, admonishes Takashi for allowing Han to steal from him. Takashi confronts Han, Sean and Neela, whereupon they flee. During the chase, Han is killed and Takashi, Sean and his father become involved in an armed standoff which is resolved by Neela agreeing to leave with Takashi. Twinkie provides his saved money to Sean to make up for Han's stolen money which Sean returns to Kamata. Sean proposes a race against Takashi to determine who must leave Tokyo. Sean and Han's friends then build a car from various spare parts and Sean wins the race. Later, Sean, now the "DK", is challenged to a race by an unnamed driver. This driver turns out to be Dominic.
