Deep within the underbelly of Paris, there is a club which is the home of a secret, wicked society. At first it resembles an ordinary fetish or Goth nightclub, but within the cavernous building are many hidden rooms, one of which is known as "The Room of Souls," a private gathering place of the world's richest and most evil people. Their host is the elegant yet frightening Madame Sabatier. For their amusement each member takes a turn and spins a true tale of depravity.

A young woman, after driving her father to suicide, is examined by the Catholic Church, who determine that the girl is in fact possessed, and a wave of priests wade in and out of the demonic gore.
