In short, it is a modern-day (i.e. World War II era) retelling of the Biblical story of Job. J.B. is a well-to-do banker with a wife and family. God and Satan (re-inacted by the characters of Nickles and Mr. Zeus) test Job by removing all that he holds dear and then by having the notorious 3 "friends" (named the same as in the biblical account) who give him reasons for his suffering. J.B. does not curse God despite his wife's requests for him to do so and finally, when she can no longer offer anything to him, she leaves also. At the end of his test, his wife, Sarah, does return and they decide to face the world together despite the fact that they still cannot see justice...only human love.
