The writer Louis Gardel remembers his youth in Algeria. In 1955, Louis is 15 years old and lives with his grandmother Zoé. Zoé is friend with president Steiger, leader of the French settlers but also with the old Arab Bouarab. One night looking at the Bay of Algiers, Louis is convinced that the world in which he has grown will disappear. The first events of the War of Independence have begun. The young boys and young girls have a good time at the seaside: swimming, dancing, flirting. But, little by little, the war becomes part of their daily life.

Alger 1955. Louis a 15 ans. Il vit chez sa grand-mère Zoé. Généreuse, bonne vivante, elle représente la joie de vivre. Zoé est aussi proche du président Steiger, le meneur des colons que du vieil arabe du village Bouarab. Un soir, devant la baie d’Alger, l’adolescent est traversé par la certitude que le monde dans lequel il a grandi est condamné à disparaître. Les premiers évènements de la guerre d’indépendance viennent de commencer. C’est la fin de l’insouciance.
