Natasha Martin (Nadia Bjorlin) is a beautiful auto mechanic and aspiring musician who is invited to join music producer Infamous (Eddie Griffin) aboard his private jet en route to Las Vegas in appreciation of her services on his Ford GT. She is also a highly skilled race car driver, but is sometimes haunted by memories of her father's death at a NASCAR race many years ago. Meanwhile, on another side of town, Carlo (Nathan Phillips) has just returned from a tour of duty in Iraq. He meets up with his brother Jason (Jesse Johnson) before heading to Vegas themselves. Carlo is not happy that Jason is living with their mob boss uncle Michael D'Orazio (Angus Macfadyen), whom he always sees as the cause of their family's destruction. Little do they know that Michael has been running an unsuccessful counterfeiting ring and owes millions of dollars to another syndicate led by the "Godfather" (David Dayan Fisher).
On the outskirts of Vegas, a high-stakes race event is being held, with Michael, Infamous, Hollywood producer Jerry Brecken (Tim Matheson) and Chinese businessman Marcus Cheng (Michael Hagiwara) placing their bets over who has the better car. When Infamous' driver fakes an ankle injury, Natasha becomes Infamous' driver in exchange for $300,000 and a recording contract. However, she is unaware that Infamous has to place her on his wager, as Michael - who has been obsessed with her since watching her band perform on stage earlier - has placed four platinum bars at stake. At the same time, Brecken wagers his brand-new Enzo Ferrari on Natasha.
Natasha (driving a Mercedes-Benz SLR McLaren) takes on Jason (driving a Lamborghini Diablo). As they approach the finish line, Natasha is several car lengths ahead of Jason, but he quickly zips past her by engaging the onboard nitrous system. Unfortunately, because of the excessive speed, the Diablo loses downforce, flies off the ground and flips in mid-air before crashing upside down at the finish line. Attempting to avoid the falling Diablo, Natasha crashes on a barrier and is knocked unconscious. Before Carlo can reach Jason to rescue him, the Diablo bursts into flames, killing his brother instantly. Michael's henchmen, dressed as paramedics, place Natasha in an ambulance and speed off.
Natasha wakes up in Michael's mansion, realizing that she is now his property. Meanwhile, Carlo meets up with an old military friend and picks up some ammunition and gear before riding a Ducati 999 with the intent to kill Michael. After breaking into Michael's mansion, Carlo and Natasha bump into each other and leave the complex. This prompts Michael to have his henchmen kidnap her mother and convince her to drive for him at the next race at Red Rock Canyon in Nevada. Meanwhile, after receiving an ultimatum by the Godfather to pay him $80 million following a botched attempt at giving him counterfeit bills, Michael raises his funds for the upcoming race by borrowing money from the banks using his mansion as collateral.
In the final race, Michael, Brecken, Infamous and Cheng place their bets for a combined purse of $100 million. Infamous and Cheng are eliminated from the race after their cars (an SLR and a Porsche Carrera GT, respectively) are involved in separate crashes. During the race, Natasha (driving Michael's Enzo) receives a phone call from Carlo notifying her that he has rescued her mother. While she is several car lengths ahead of Brecken's Saleen S7 Twin Turbo, she stops the Enzo an inch away from the finish line and gives the S7 the win, costing Michael the race.
With no money left, Michael is given a last ride from the Godfather's henchmen. As a way of thanking Natasha for handing his driver the victory, Brecken gives her a recording contract (which shortly gives her a gold record and lands her on the cover of Variety), an Enzo and a Koenigsegg CCX. The film ends with Natasha (in the Koenigsegg) and Carlo (in the Enzo) racing each other before being chased by the police on the freeway.
