At a bustling racetrack, aging drag racing sensation Lonnie "Lucky Man" Johnson, portrayed by William Smith, is eager to fine-tune his car, backed by the international oil giant Fast Co. However, during its inaugural test run, the vehicle meets a catastrophic fate, exploding spectacularly while Lonnie miraculously escapes unscathed, truly living up to his moniker. Fast Co's team leader, Phil Adamson (played by John Saxon), is far from impressed. He expresses his frustration to the head mechanic Elder (Don Francks), emphasizing that their budget is at stake and that the car must remain competitive to ensure sales of Fast Co products.
In the competitive Funny Car class, Lonnie's protégé Billy "The Kid" Brooker, brought to life by Nicholas Campbell, is giving a tough fight to the reigning champion Gary "The Blacksmith" Black (Cedric Smith). During their road trip to Big Sky, Montana, Lonnie eagerly reaches out to his girlfriend Sammy (Claudia Jennings), who is in Seattle, conveying his sense of longing for her. Trouble arises when the Fast Co rig incurs a flat tire; Black, envious of Lonnie's financial success and fanfare, declines to lend a hand.
The drama intensifies as Adamson arrives in his private aircraft, accompanied by Candy Ellison (Judy Foster), the charming new advertising face for Fast Co. At the Big Sky racing event, Adamson is seen taking a bribe from the organizer, declaring, "The Fast Co team sell tickets at his mosquito patch. If you don't want us to continue..." This demonstrates the pressure to maintain their prominent status. As the repairs on the dragster linger, Adamson takes it upon himself to have Lonnie replace Billy in the Funny Car—an idea Lonnie resents, while Billy feels overshadowed and blames Lonnie's inflated ego.
In a twist of fate during Lonnie's debut Funny Car race, he competes against Black, who is irate over the last-minute driver switch. As tensions heighten, Billy finds solace in flirting with Candy. However, chaos ensues when Lonnie learns that repair work has been halted on his dragster, causing further discord.
During the next race, Lonnie expresses his dissatisfaction with his Fast Co sponsorship, infuriating Adamson, who considers bringing Black on board. The conflict escalates when Candy is fired for refusing to engage in unsavory acts for damage control, leading to her and Billy finding comfort in each other. When Sammy unexpectedly arrives to confront them, misunderstandings spiral into chaos.
Amidst family turbulence, Lonnie and Sammy reconnect, leading to a heated confrontation with Adamson, which results in Lonnie striking him. Despite appearing to be at an impasse, Lonnie vows to keep racing, but Adamson's machinations to replace him continue—involving shady tactics like sabotage by Meatball, the team mechanic.
After a test run disaster, tensions peak, and a heated rivalry ensues between Lonnie and Billy against Black, leading them to steal back their prized car from Adamson. Their determination shines through as they prepare for the next race in Edmonton, Canada.
The night of the race arrives, and as fate would have it, blackmail and treachery culminate into a fiery incident when Black's car meets a dreadful fate due to foul play. In a dramatic turn of events, Lonnie takes a daring flight to confront Adamson while the chaos is unravelling, ensuring justice for his team and their aspirations.
With the sun rising on a new day, the team reflects on the future. Lonnie promises new investments are on the horizon as he cherishes a moment of intimacy with Sammy, while Billy and Candy look forward to their own escapade. As Elder and PJ remain vigilant with the car preparations, the stage is set for more thrilling adventures ahead.
