The Thompson-Thorpe automobile was once a great car but dissension between the owners led to the break-up of the company, and Thompson and Thorpe have each started their own car-manufacturing company. Not knowing his true identity, Earle Thorpe Jr. has been hired by Henry Thompson to drive his new car in an upcoming race. Unknown to Thompson has two crooked mechanic/engineers on his payroll who plan to make their own car, using Thompson's plans, and win the big race themselves. Etta, Thompson’s daughter, and Earle team up to re-unite Thompson and Thorpe Sr. by taking the best features of both cars and combine them into one super car.
