O is een jonge, levendige fotograaf die verliefd wordt op Rene. Hoewel hun relatie in eerste instantie lijkt op een romance uit een verhalenboek, verandert alles wanneer hij haar naar een plaats stuurt die Roissy heet, waar vrouwen worden onderworpen aan intensieve fysieke en psychologische SM-training om van hen de perfecte slaven te maken.
