of her notes, in which she says that she only makes films because she lacks the courage to do nothing. Paul says this is true for himself as well. The celebrity then gets Paul to take her back to the airport, after which he has to face a furious Denise who has lost her interviewee. That evening, as it is Cécile's birthday, he takes her and her mother to a restaurant but all his scornful ex-wife wants is money and all the girl wants is presents. Leaving in fury, after again expressing his alienation with inappropriate sexual innuendo, he meets Denise in a bar, where the two quarrel and part. Standing alone in a late-night cinema queue, he is picked up by the prostitute Isabelle. Part Three, "Commerce," is Isabelle's section, in which she devotes herself to increasing her earnings in order to achieve independence. After her night with Paul, in which she mechanically goes through the motions while mentally planning her next day, she is waylaid by a pimp who gives her a spanking to remind her that there is no independence in a commercial world and he must have 50% of her earnings. On returning to the apartment she shares with some other women, who all seem to detest her, her younger sister arrives unexpectedly and asks Isabelle for money because her lover and all his associates have just been jailed for robbing a bank. When Isabelle refuses, the sister asks if she will get her started in the local prostitution business. Isabelle agrees to coach her for a month, in exchange for 50% of the take. While continuing to service a variety of clients with different needs, sometimes inventive (one businessman choreographs a foursome while sitting at his desk), and all the while with her mind elsewhere, she is also searching for an apartment of her own. An old school friend she meets in a hotel corridor, probably a dealer and maybe a prostitute as well, offers her a lucrative opportunity to be a courier, but the boss of the operation finds Isabelle too dangerously naive. Going to inspect an apartment, it turns out to be that of Denise, and Paul is also there trying to rekindle the relationship. Isabelle and Denise form an immediate bond. In the coda, entitled "Music," Isabelle seems to prosper in her new apartment and Denise has moved on in life. After
