Camp de Thiaroye: A Senegalese platoon of soldiers from the French Free Army are returned from combat in France and held for a temporary time in a military encampment with barbed wire fences and guard towers in the desert. Among their numbers are Sergeant Diatta, the charismatic leader of the troop who was educated in Paris and has a French wife and child, and Pays, a Senegalese soldier left in a state of shock from the war and concentration camps and who can only speak in guttural screams and grunts.
