Jennifer is an upwardly mobile psychiatrist married to a divorce lawyer named Duke. Each of them has their work cut out for them at their offices, and they project themselves into the stories their clients tell them.

Justine Jones, in a continuation of The Devil in Miss Jones, Part 1 (1973), is frustrated in hell. She makes a sexual deal with the Devil himself to earn a return to earth as an immortal human. However, in earning her escape, Lucifer falls in love with her. He doesn't want her to go but can't admit it because he's the Devil. The story gets underway as he tries to place her soul in nubile bodies on earth that are increasingly removed from opportunities for sex, in order to jealously deny her the one thing she craves. He finally tries the body of a nun, but this brings him into conflict with HIM, resulting in a humorous finale.

After a man dies he is offered the chance to return to Earth in the bodies of other men.
