Paris, 1871. This is a story of the women trapped in a luxury brothel, 'Paradise'. The very young Rose came to Paris in search of her mother, former prostitute. She is trapped and forced to enroll in Paradise. Vera is 35 years. She knows that the end of her career as a prostitute is near. She is betting everything on the Baron Du Plessis, her main client, and the only one able to redeem her debt. Hortense is the owner of Paradise. She must take care of her girls and resist pressure from a suburban thug who is charging her money.

Fired for insubordination, PJ Antoine Verlay, good cop but a blood strand and having difficulty working as a team, is attached to the OCBC (Central Office for the fight against Traffic in Cultural Goods) thanks to the intervention of the commander Pardo, his friend who becomes, therefore, his new superior. A clever investigator, but a stranger to everything related to culture, Antoine will have to work with Florence Chassagne, renowned art historian, who lives, speaks and breathes culture, to the point that - fruit of her great imagination - it happens to her in the midst of daydreams, to see and talk to the great artists who have disappeared as if they were familiar to her.
