The story in this inventive and critically well-regarded film is told backwards, beginning in the 1980s and detailing the lives of two couples who were deeply affected by the popular song of the 1960s "Besame Mucho". From then until the 1980s, pop music defines the key moments in their lives. The effects of each situation are shown first, and then the causes are gradually revealed, culminating with the characters' college years.
