Plot
Twin brothers Rafe and Victor are two truckers who have had a bad run of luck: they have a history of missed deadlines and are tormented by a loan shark named Sweeney, who repeatedly tries to repossess their truck. After yet another late delivery due to rushing a pregnant hitchhiker to the hospital, the pair are given one final chance by their boss, who orders them to ship barrels of toxic waste from the company Tech Star to a ship docked in California. To remind the brothers of the deadline, their boss fits a digital countdown timer, which he dubs "foul-up clock", to the truck's dashboard.
Tech Star is a company that uses child geniuses as slave labor. One such slave, named Holly, has invented a device that resembles an ordinary remote control yet can activate and deactivate any electronics by code. The brothers arrive at Tech Star and, while they are loading their truck, Holly stows away in the cab, having learned the shipment is destined to the same place where her fiancé lives. She is soon discovered, and while Rafe and Victor agree to protect her, they fail to understand her invention. They spend the night in a Texas motel, nearly eluding Dr. Bruekner, the CEO of Tech Star, and his hired goons, who attempt to recapture Holly as her invention is Tech Star property. Later, the brothers' truck stalls on the railroad tracks as a train is approaching. Holly struggles to remember the right code to restart the truck's engine with her invention, doing so at the last minute, but the trio fails to realize that she inadvertently entered a code that reprogrammed the foul-up clock two hours back.
