Bertrand, a handsome young man who works as a male prostitute in Paris, leaves an elderly writer dead in his bath and steals the typescript of his just-finished play. Selling it to a publisher as his own work, it proves a success. Both the work and the apparent author greatly impress the publisher's assistant Caroline, who soon has Bertrand sleeping in her flat.
The pressure is now on Bertrand to write a follow-up, and he retreats to a mountain chalet to work. There he meets an older woman who completely fascinates him. This is Eva, who lives in her husband's elegant house and works as an expensive prostitute. She says her husband is on a prolonged business trip, but it is revealed to viewers that he is in jail. Obsessed by the enigmatic character of Eva and the things she tells him, Bertrand tells his publisher that she will be the subject of his next work. The publisher secretly books a session with Eva to see if she is real.
Caroline, sensing that Bertrand is avoiding her, turns up secretly at the chalet and finds Eva in the bath. Rushing away in despair, she crashes her car and is killed. Bertrand goes secretly to Eva's house, where a stranger beats him up so thoroughly that he is hospitalised. When released, he sees Eva in the street with a man viewers know is her just-released husband. She signals wordlessly to Bertrand to keep away.
