Two travelers, Boualem and Sekfali, cross the hostile and endless desert. Boualem pulls a cart on which old books, pictures, relics and memories of Sekfali are piled up. Two men, two attitudes towards life, two visions of the world. Where do they come from, where are they going? The journey would be completely calm and happy if each of them were not inhabited by their pasts, determining their different visions of the future. Boualem's childhood was marked by the Algerian war of liberation. His dream is to achieve a socialist society, which is for him the only path to salvation. Sekfali, who tries to dissuade Boualem from continuing the journey, has the attitude of an aristocrat. For him, socialism is a heresy and people do not like responsibility, they only act if a leader gives them the injunction.
