This seems like a sequel to Étreintes à la prison de femmes where Laura Valérie is investigated by the press about the goings on at the prison involving Marie Noelly. But there are lots more complications than that.
Carole discovers the world of a prison of women, women willing to do anything to gain a few moments of oblivion, or moments of ecstasy, a world of everyone for himself with its procession of humiliations, constraints and pleasures stolen.
