Set in Belle Époque France, the story follows nineteen-year-old "hysteria" patient Augustine, the star of Professor Charcot's experiments in hypnosis, as she transitions from object of study to object of desire.

The dawn of the 20th century: L’Apollonide, a luxurious and traditional brothel in Paris, is living its last days. In this closed world, where some men fall in love and others become viciously harmful, the women share their secrets, their fears, their joys and their pains.
