Successive Slidings of Pleasure
Glissements progressifs du plaisir (original)
A young woman is suspected in the stabbing death of her roommate Nora. Imprisoned in a convent, the girl’s seductive wiles hypnotize the cops and clerics that surround her. All submit to her sexual whims, and are drawn into a sado-masochistic world where fantasy and reality are pleasurably blurred.
