A young boy plays matchmaker for his widowed father.

Recently widowed Tom Corbett, advertising director of a radio station, hires a day housekeeper to help care for his 6 1/2-year-old son, Eddie. The boy, however, would like his father to become romantically involved with a woman such as their attractive neighbor, divorcée Elizabeth Marten, who nursed Eddie when he was ill. When Eddie fails to interest his father in a relationship with Elizabeth, he strikes up a friendship with a shy beauty contestant from Montana, Dollye Daly; but she falls in love with Norman Jones, a disc jockey who is also a friend of Tom's. Tom next meets Rita Behrens, a chic fashion consultant of whom Eddie disapproves. When Tom announces that he plans to marry Rita, Eddie runs away from summer camp and takes refuge in Elizabeth's apartment. As a result, Tom breaks with Rita, and little Eddie at long last makes his father realize that Elizabeth is the best possible choice for a wife.
