After learning that niece Kelly is becoming attached to another family down the street, Uncle Bentley endeavors to spend more time at home with her. He even arranges a surprise outing with Jack Benny.
13-year-old Kelly is going out on her first date, and her Uncle Bentley becomes a bundle of nerves after he learns that the boy is a 15-and-a-half-year-old version of himself.
Kelly feels that she is now old enough to be treated as the woman-of-the-house. Meanwhile, her girlfriends vote to present a humanitarian award to their heartthrob, Ronnie Burns, the son of George Burns.
