Eduardo, a man about to get married to his lifelong sweetheart, begins having second thoughts about the step he is going to take. His future wife is not one-of-a-kind and, among the wedding guests, there are several women he would not mind spending the rest of his days with. So, while the ceremony carries on, he fantasizes about the lifestyle he could experience with some of them.
Lucas, typical average Spaniard, shy, gray and repressed, is married to sanctimonious Enriqueta, so he is always aware of other women, although the couple are already parents of nine children, which is why Lucas will do the unspeakable to convince his wife to take the contraceptive pill, something practically sinful for a practicing Catholic like Enriqueta.
