When beautiful kitchen maid Augustine (French recording artist Soko) suffers an inexplicable, violent seizure, she is sent to a psychiatric hospital specializing in the treatment of feminine "hysteria" and presided over by Dr. Jean-Martin Charcot (a founding father of modern neurology and a mentor to Sigmund Freud). Fascinated by his new patient, Charcot (Vincent Lindon) quickly makes Augustine the star attraction in a series of hysteria presentations, hypnotizing her to induce spectacular fits for crowded lecture halls. As the full nature of Augustine's affliction begins to emerge, the relationship between doctor and patient becomes more complicated and personal power dynamics start to shift. Based on a true story from late 19th century Paris, Augustine is a lush, darkly sensuous tale of romance, psychology, and sexual politics.
