"No one loves anyone for more than two years" is an adaptation of Nelson Rodrigues' work about five couples that live in Brazil in the early 60's, who are seen by the society as conventional people, but whose intimate lives turn out to be morally questionable.
Ulisses has failed in his professional life, but leads a happy life with his wife Ângela and their two daughters. Until the day he is introduced to Bárbara, a very beautiful woman living in Rio de Janeiro. Ângela becomes her friend and gives her the dress Ulisses had given her. From then on, marital problems arise, and he becomes increasingly attracted to Bárbara.
