For nine months in 1930, seven Bretons, lobster fishermen, were "forgotten" on a volcanic island by their employers, Normans from Le Havre, heirs of the last French whalers. Four employees would die on the spot. Their descendants today revive the memory of this human tragedy which also struck 42 Madagascans. Starting from a sordid social conflict, the documentary shows that the “Forgotten Saint Paul” mark the end of an era of “colonization”, a term rarely used for the French Southern Territories, but nevertheless close to reality. This is the story of the Third World, as its discoverer, Yves de Kerguelen, named it.
