Siempre felices

Patricia and Alberto are a young couple. Patricia reads Nietzsche and theorizes on men, women and the perfect crime. Alberto believes in marriage, but not exactly in his own. Patricia wants to have lovers, but without losing her husband. Albert wants another woman. Both meet their respective lovers on the same day and at the same time. From then on, things start moving and different characters appear and disappear, a comic outlook on the war of the sexes.
