On the shores of the Bouches-du-Rhône, two lovers film each other in the burning garrigue of the Mont Rose, a large limestone rock beaten by the sun, before reaching the Camargue, a salt-laden landscape, more deserted, made of windy dunes, shreds of riparian vegetation and swamps. Their journey ends at the lighthouse of Beauduc, isolated between the ponds and the sea, to test their desire.
