Jeanne Poisson, the headstrong, ambitious, witty and erudite, catches the eye and heart of French King Louis XV at a costumed ball. She masters the art of seduction well enough to become accepted even by the Queen, corpulent mother of ten. As a sensibly chosen Royal 'favorite' mistress she is soon ennobled Marquise of Pompadour to facilitate her introduction at court. The immature dauphin (crown prince) proves a bitter and unrelenting enemy, joined by his imposed Saxon bride, and his sister at her deathbed. Although friends at court help Pompadour return, her health gives way.

Paris, France, 1979. Rose, a rebellious orphaned teenager, and Michel, a young aspiring painter, enjoy their crazy love under the neon lights of the decadent nightclub Le Palace, where they establish an ambiguous relationship with Lucille and Hubert, two bohemian bourgeois who will change their lives.

Jeanne is a young woman, striking but otherwise without qualities. Her mother tries to get her a job in the office of a lawyer, Bleistein, her lover years ago. Jeanne fails the interview but falls into a relationship with Franck, a wrestler whose dreams and claims of being in a legitimate business partnership Jeanne is only too happy to believe. When Franck is arrested, he turns on Jeanne for her naivety; she's stung and seeks attention by making up a story of an attack on a train. Is there any way out for her?
