Tobey Marshall is a former race car driver who owns his late father's garage, Marshall Performance Motors, in Mount Kisco, New York, where he and his friends tune performance cars. Struggling to make ends meet, he and his crew participate in street races after hours. After a race, Tobey's former rival Dino Brewster conscripts them into completing the build of a rare Ford Shelby Mustang worked on by the late Carroll Shelby, in exchange for 25% of the car's sales revenue. The completed Mustang is displayed for auction at a party in New York City. Tobey and Dino meet Julia, an English car broker whose client, Bill Ingram, wants to purchase the car if they can prove it will drive over 230 mph, as Tobey claims. Despite Dino's objections, Tobey takes the Mustang to a local race track and successfully drives it at 234 mph, convincing Ingram to purchase it for $2.7 million.
