David Mann, a middle-aged salesman driving on a business trip, encounters a dilapidated tanker truck in the Mojave Desert. Mann passes the truck but the truck speeds up and roars past him. When Mann overtakes and passes it again, the truck blasts its horn. Mann pulls into a gas station and the truck parks next to him. Mann phones his wife, who is upset with him after an argument the previous night. The station attendant tells Mann he needs a new radiator hose but Mann says he will get it done later and declines the repair.
