Young David Morton, heir to millions, has been overzealously restrained from normal youthful activities by his two old-maid aunts, Harriet and Agatha. In a break from his confinement, he meets lovely Gertrude, and promises to race her injured brother's car in the Big Race. Between the gangsters trying to win the race by disabling him, and his bungling bodyguards trying to bring him home safely, David has a battle to win the race and Gertrude's heart. He succeeds in winning the race, capturing the gangsters, and getting his aunts to give him more freedom.
