Dominic Toretto (Vin Diesel) drives the streets of L.A. as if he owns them. As far as his crew is concerned, he does. He spends his days putting wrench-time into high performance racing cars - make and model matter less than the computer-controlled fuel injection that makes them fly. Nights, Dom pilots his own earth-bound rocket, pocketing as much as $10,000 a ride when somebody has the nerve to race him. Brian (Paul Walker) is hooked, hungry and ready to test the limits, too. He prides himself on street smarts, but to this crowd he's white bread. He seeks Dominic's approval behind the wheel of his own NOS-injected muscle machine. After a blazing encounter with ruthless Johnny Tran (Rick Yune), Dominic decides Brian is all right. Dominic's sister Mia (Jordana Brewster) likes what she sees, too. The thing is, they don't know he's not the same inside as his outward appearance!
