Don't Deliver Us from Evil

Two adolescent girls at a Catholic boarding school, Anne de Boissy (Jeanne Goupil) and Lore Fournier (Catherine Wagener), are drawn toward increasingly evil deeds, engaging in malicious pranks, petty theft, and eventually plotting a heinous crime. They prepare an abandoned chapel for a Black Mass, sealing their bond with a pact of devotion to Satan, and later plan a suicide pact, convinced they will go to Hell and be rewarded by Satan for their service.
