Dominic Toretto is a Los Angeles street racer suspected of masterminding a series of big-rig hijackings. When undercover cop Brian O'Conner infiltrates Toretto's iconoclastic crew, he falls for Toretto's sister and must choose a side: the gang or the LAPD.

It's a major double-cross when former police officer Brian O'Conner teams up with his ex-con buddy Roman Pearce to transport a shipment of "dirty" money for shady Miami-based import-export dealer Carter Verone. But the guys are actually working with undercover agent Monica Fuentes to bring Verone down.
