The film's plot is centered on a street racing circle funded by a group of multimillionaires who wager millions of dollars over their high-powered sports cars.

Natasha Martin is an auto mechanic and aspiring musician who is invited to join music producer Infamous aboard his private jet en route to Las Vegas in appreciation of her services on his Ford GT.

Meanwhile, on another side of town, USAF veteran Carlo, returning from a tour of duty in Iraq, meets up with his brother Jason before heading to Vegas themselves.

On the outskirts of Vegas, a high-stakes race event is being held, with Michael, Infamous, Hollywood producer Jerry Brecken and Chinese businessman Marcus Cheng placing their bets over who has the better car.

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.

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.

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.

After seeing many mortgage brokers buy cars from the Mercedes-Benz dealership he worked at, Sadek entered the real estate business and set up the subprime lending firm Quick Loan Funding in 2002.

[5] He used his earnings to buy several homes in Southern California and Las Vegas, build his collection of expensive supercars and feed his insatiable appetite for gambling.

[3] Using his subprime lending firm as his source of funding,[6] he produced the film Redline to show off his car collection and help Bjorlin break out of the soap opera scene.

"[15] The film has also been released on Blu-ray outside the U.S.[16] In the CNBC special House of Cards, the crashing of two US$500,000 cars for a single scene is cited as a direct example of the excess of the pre-crash subprime loan market in the mid-2000s.

[17] Following the demise of his company, Sadek lost his escrow and lending licenses over issues of him withdrawing millions from his corporate accounts to gamble in Vegas.
