A doctor tries to cope with his wife's newfound stardom as an advertising pitch woman.

Beverly Boyer is a thrifty housewife living contentedly with her gynecologist husband, Gerald, and their two small children. One evening while dining at the home of Mrs. Evelyn Fraleigh, one of Gerald's patients, Beverly comments on the fine qualities of "Happy Soap," a product manufactured by Evelyn's father-in-law, Tom Fraleigh. The old man is so impressed by Beverly's enthusiasm that he hires her to do soap commercials on his television show. After an unfortunate start, Beverly's honesty and sincerity wins praise from both viewers and critics. Elated, old Fraleigh signs her to an $80,000 contract. Now a public celebrity, Beverly is forced to spend more and more time away from home; and trouble erupts at the Boyer household. The final blowup comes when Gerald accidentally drives his car into a swimming pool that had been installed in his backyard that afternoon. Outraged, he kicks cartons of "Happy Soap" into the pool and by morning the house is surrounded by soapsuds. After consulting a psychiatrist, he decides to get even with Beverly by pretending also to be too busy to spend time at home. His scheme works, and Beverly becomes so frantic that she forgets the name of the soap she advertises. The couple are reunited in the back seat of the Fraleighs' Rolls-Royce, and there Gerald delivers Evelyn's baby during a traffic jam. Beverly decides to quit her job and return to her role as wife and mother.
