Director Philippe Prigent invites us on a voyage, played to the rhythm of the undulated dunes of the Moroccan desert. The immense landscapes seem frozen for eternity, carved by capricious winds. Sand stretches as far as the eye can see; yet a campsite of tents rises up within the hollows of the dunes. Several desert enthusiasts offer us a different kind of tourism from the traditional circuits, with the ethereality of an installation that will leave no trace on the Saharan landscape - a return to essential living in an ocean of sand.
