Dominic Toretto (Diesel) is the leader of a gang who races cars for money. By day, he works on his racing cars with computer-controlled furl injection. At night, he races against anyone with the nerve, as hundreds of onlookers cheer on the sidelines. With each win, he pockets $10,000.

Brian (Walker) is trying to enter the gang, and to do that he needs the approval of Dominic. What the gang doesn't know, however, is that Brian is an undercover cop investigating a series of big-rig hijackings. As Brian keeps close watch over Dominic and a rival gang leader, Johnny Tran (Yune) a strong attraction between he and Dominic's sister, Mia (Brewster), intensifies. With heart and head at odds, he must decide where his loyalties lie.
