Racing Hearts.

Automobile maker John Kent is an old-fashioned sort who refuses to advertise his car line. His daughter Ginger, however, is determined to get him some publicity and goes speeding around town in one of his cars, hoping to get arrested. Roddy Smith, posing as a cop, stops her. His father owns a rival firm and he suggests that Ginger convince her father to enter his car in the Vanderbilt road race.
