Michael Faversham, a puritanical minister determined to stomp out immorality, orders one of his parishioners, Rose Gibbard, to confess in public that she is the mother of an illegitimate child, knowing that it will bring shame and condemnation to her. Meanwhile, he is consumed with desire for another of his parishioners, the lovely Audrey Lesden. One day the two of them find themselves alone on a deserted island, and the attraction of Faversham and the married Audrey for each other is too difficult for them to resist. Complications ensue.
