In this film, four key witnesses, who live in Algeria today, as full-fledged Agerians, show us what this colonization was really like, so "beneficial" that they themselves perceived it as the oppression of one people by another. Three of them, who today would be called "pieds noirs," in other words, those Europeans to whom France, the occupying power, gave the best land, taken from the indigenous populations, work, and exclusive rights, not shared by the entire population, lived rather well compared to the majority of the "natives." The fourth was far from all that and lived in Argentina. Annie Steiner, Felix Colozzi, Pierre Chaulet, and Roberto Muniz explain to us what led them to show solidarity with the struggle of the weak, the humiliated, and to risk their freedom and their lives by committing to liberate Algeria.
