Thorne Smith pits two thoroughly modern married people in a classic battle of the sexes. After listening to the nearly endless bickering and childish jealousy of a young man and wife (Tim and Sally Willows), an ancient Egyptian idol decides to play a trick on the two by causing them to switch bodies. Like Thorne Smith, Tim works in an advertising agency, and several scenes are set there, drawing on the author's experience. After the wife forcefully impregnates her husband, things take a decided turn for the worse as they separately try to deal with the object of the former wife's affections-a deplorably predictable square-jawed philanderer by the name of Carl Bently.
