Old Indy meets a man driving a monster truck with the biggest set of wheels he ever saw at the gas station. He is reminded of his own teenage dream of driving the hottest car to his junior prom in 1916: a Bugatti owned by his then girlfriends father, Edward Stratemeyer. While trying to get the engine repaired, Indy and Nancy helped solve a robbery case from Thomas Edison's laboratory. It seemed German spies were after Edison's new electric motor.
