Pedro, a young psychology intern is placed in the largest female prison establishment in the country. Looking fragile and naive, early his posture contrasts with the hostile, aggressive climate surrounding him. In this prison, women from a diverse range of social backgrounds are being held for many different crimes. All of them mothers, women and people coexisting in the same physical space, with nothing to distinguish them to begin with. Pedro’s arrival at the prison establishment causes sensation. But quickly it becomes clear that after all his naiveté is not void of strong convictions and principles.
