Waking from a coma in a private clinic with amnesia, a man is told that he survived a car crash and that he is Georges Campo, a name he does not recognise. A beautiful woman he does not know, who says she is his wife Christiane, takes him to recuperate in a mansion in walled grounds. With her is a doctor, Frédéric Launay, who says he is an old friend from their days in business together in Hong Kong. At the mansion they are greeted by the half-Chinese butler Kim, who is offhand with him but has a suspiciously close relationship with Christiane. He is told that he must rest and take copious medication, while Christiane adds that there is no hope of any marital relations until he is fully well.
