Thriller written and directed by Alain Robbe-Grillet.
Alice (Anicée Alvina) and Nora (Olga Georges-Picot) experiment with bondage and creating human art together using various substances.
But Alice becomes the chief suspect in a murder investigation when their flat is broken into and Nora is seemingly killed by the intruder with a pair of scissors while she is tied to the bed.
Once questioned by the police, a judge and a priest, Alice is sent to a convent prison and interrogated on suspicion of being a witch.
The judges may just be proved right as those inside the walls of the convent also begin to fall under the spell of Alice's charms.
