 Racing car enthusiast Jerry O Connor and his dim-witted mechanic, Buddy Buttle, get their chance to join the crew of race car builder Pinky Delano, who just suffered a setback when one of his drivers was killed by failing to make a turn on the track. Then, one by one, his other drivers suffer the same fate, until it is Jerry s turn to drive in the big race. Buddy tries an experiment and determines these were no accidents but is it too late to help Jerry, who has started the race?
