He changes his mind when Jack Blodgett (Tommy Bond), the local speed demon, impresses David s girl, Janie Pitts (Gloria Winters), and David makes his car the fastest in town. Jack steals David s hot rod, and flees the scene of an accident he causes. The car is traced back to David, but the truth comes out in court, although David s father is still unhappy about the car...until David and his friend, Swifty Johnson (Gil Stratton Jr.), use it to apprehend some escaping robbers. The Judge decides to back a movement for building a hot-rod race track for the town.
