Sandrine is a sharp, young professional trapped in a passionless, entirely predictable routine alongside her long-term boyfriend, Fred. Deeply dissatisfied with her unfulfilling domestic life, Sandrine's world shifts when her friend Françoise introduces her to the concept of uninhibited sexual experimentation. Driven to break free from societal and relational constraints, Sandrine acts as a cheating girlfriend to shatter her mundane reality before severing ties with Fred entirely. Wandering a Parisian park, she encounters Greg, a charismatic psychoanalyst who utilizes deep hypnotic therapy to unlock the suppressed mechanisms of human desire. Submitting to Greg's techniques and joined by his liberated former lover, Sophie, Sandrine embarks on a bold, hallucinatory odyssey into the absolute outer limits of her carnal imagination, permanently trading her quiet domesticity for a realm of spiritual and physical ecstasy.
