Teresa is a young, always cheerful woman, who has a harmonious marriage with the writer Peter Duhren. Unfortunately, it’s so harmonious, that he’s uncapable of writing a novel. So he decides instead to write a book about his own marriage. Teresa is so horrified about this indiscretion, that she asks for a divorce. Peter is prepared to withdraw the book from circulation to save his marriage, but when he finally is about to do so, it becomes a bestseller. Despite attempts at reconciliation, Teresa leaves his. So much for the alleged ‘harmonious’ marriage.
