Plot Summary
Dominic Toretto (Diesel) is the leader of a street racing gang that is under suspicion of hijacking trucks for their cargo of expensive electronic equipment. Undercover cop Brian O'Conner(Walker) attempts to find out who exactly is stealing the equipment by infiltrating the local racing community with the help of a local auto parts dealer, while falling for Dominic's younger sister Mia (Jordana Brewster).
After O'Conner loses his Mitsubishi Eclipse to Toretto in a race for "pink slips" (a 1950s slang term for the registration documents for a car in the United States) and then loses it again when they are confronted by Toretto's rival Johnny Tran (Rick Yune), O'Conner tries to gain the trust of Toretto by working on repairing and upgrading a burned out Toyota Supra to hand over to him. While doing this, O'Conner is constantly pressured by his superiors in the LAPD and the FBI to bring the investigation to a satisfactory close, leading him to face a stark choice between the community he has embedded himself into and the woman he has become close to, or discarding his cover and discovering who from the street gangs is carrying out the hijackings.
