All of the inhabitants of a Portuguese mental asylum suffer from religious delusions of one kind or another -- even the cynic who denies the value of any religions at all. One couple re-enacts the story of Adam and Eve in the Garden, and then the woman who played at being Eve plays at being St. Teresa de Avila. Another man thinks he's a character from a Dostoyevsky novel, and yet another claims to have in his possession a fifth gospel from the Bible. Everyone has a point of view and is not shy about stating it, defending it in debate with the others with great sincerity, though with very little elegance or wit.
