North Africa, the Aures Mountains, 1885. This fable is set in arid desert shades, made of ravines and gorges, struck by a blazing sun. In a lost colony, near the Sahara, where a war has just ended, the doctor Max Orswell returns from the front, broken by eight years of service. He is waiting for one thing more, the boat that finally brings him home. He shuts himself up in a room, waiting for the caravan to port Hebili. The days pass, the caravan does not come. Things capsize. A corpse appears in the street. Another. Max must face the terrible facts: the horror is back.
