In a desert landscape, among the ruins, children play hide-and-seek. The remains of walls and a few abandoned objects seem to bear witness to a civilisation that has long since evaporated. Francesca, the youngest of the group, is marked by the discovery of a dead fish which becomes the object of the other children's games. The next day, back at the site, the little girl discovers that other people have been attracted to the remains that the disappearance of this huge artificial lake has revealed.
