The Reardons are a typical American family whose eccentricities, if hilarious, are only normal. Laura, the mother, is a social climber. The youngest, Penelope, is a demon with a slingshot and the piano. Harry, the son, is positive he is the second coming of Shakespeare. Reginald, the father, would rather tinker with the automobile than ticker tape; and Nana, the wisecracking grandmother, is only concerned with Bing Crosby records.
