A writer moves into a housing development to study married couples.

Adam J. Niles, a writer noted for his series of racy books on the sexual mores of foreign peoples, finds himself in debt to the Internal Revenue Service because of a dishonest personal manager. Forbidden to leave the States, he changes his name, moves into Paradise Village, a California housing development, and secretly begins compiling material for a book on how Americans live. The only bachelor in the community, he quickly becomes the center of attention among the bored housewives. Though his activities are watched with suspicion by Rosemary Howard, the community's secretary, Adam organizes a discussion group in which he advises the women on how to bring romance back into their lives. When the jealous husbands try to have him evicted, Rosemary, who has finally been won over, quits her job and becomes Adam's secretary. Eventually Adam's tax problems are solved, but in the process his true identity is revealed, and he is involved in three Paradise Village divorce suits. Aided by Rosemary's testimony and the enthusiastic support of three wives, Adam persuades the presiding female judge of his innocence. The three wives return to their husbands, and Adam declares his love for Rosemary.
