On a hot summer day in an empty Madrid, during a time of social and political transition in Spain, Miguel (Jose Sacristan), a feared and respected journalist, sets up a meeting with Angela (Maria Valverde), a young journalism student. His intentions are clearly sexual, but hers are less clear. A series of events force them to stay together for more time than they would have chosen: locked in a bathroom, naked, without the possibility of escape. Removed from the outside world, the two, who represent polarizing generations, are trapped in an uneven balance involving age, intellect, ambition and experience. The political and social context of the period provides the background to the power shifts that continually take place between them over twenty-four hours.
