Paris, 1871. Vera, the star attraction of the The Paradise luxury brothel, is about to finally leave the institution to become the live-in mistress of the Baron Du Plessis. However, The Paradise owes money to a dangerous debt collector named Lupin, and its madam, Hortense Gaillac, is willing to resort to absolutely anything to keep her. Meanwhile Rose, a pretty young woman engaged to be married, arrives at The Paradise” in search of her mother and Hortense sees an opportunity to revive the business.

Forced into service at The Paradise, Rose manages to escape before being tracked down by the police. After one of the girls is assaulted, Véra organizes a strike in protest, causing a strain on the brothel’s finances. In response, Hortense decides to sell Rose’s chastity to the highest bidder. As things are heating up, Hortense’s despised brother, Pierre Gaillac, arrives from the colonies to take over the business.

Hortense’s detestable brother Pierre, recently arrived in France, quickly resolves the strike organized by the ladies of The Paradise. But the calm in the storm is only temporary. Now back to work, Rose finds herself struggling to adjust to her new life. Meanwhile, Véra notices that Angéle is wearing jewelry that had previously belonged to her late lover. Suspicious, she goes to the police to report it.

Hortense must defend against the machinations of Pierre, who wants to leverage the Paradise for his own gains. A police investigation is launched in response to Véra’s claims and two girls are arrested. One day, Rose finds a photo of her mother in the house archives, and it is suggested that her mother and Hortense once shared a close personal relationship.

Pierre continues to use The Paradise to serve his own purposes, inviting many wealthy clients on his own accord. Hortense is furious and attempts to spite him by keeping the ladies locked in their rooms. Rose, always in search of information about her mother, presses Hortense, who reveals her mother’s true identity.

Angéle’s fiancée, Brise Caboche, is desperate to obtain her freedom and blackmails Hortense, who has no choice but to ask her brother for money. However, he is not immediately willing to help a sister who shows public disdain for him. Meanwhile, Rose confides in Véra how she plans to escape The Paradise: seducing Pierre.

Hortense wants to terminate Angéle’s pregnancy, but the other women band together to allow her to keep the baby. Believing her mother to have died at The Paradise, Rose seduces Pierre in an attempt to gain her freedom. But soon Pierre’s wife arrives at the brothel to confront her husband’s mistress, thinking it is Véra.

Pierre will stop at nothing to save himself and begins to entertain the most outrageous customer requests. Hortense mounts a strong opposition, aided by Véra and Rose. Along the way, Rose finally discovers the truth about her mother…and her own past.
