What to do if your life begins to resemble a cheap horror movie? If in an underground passage you meet a ghost with a volume of Nietzsche, and in the entrance - a translucent maiden? Former circus performer Kim finds those who can help - a group of esoteric firemen. An attraction immediately arises between her and the fire-worshipper Asmodeus, and this angers her old rival Ingrid, who secretly practices magic. Asmodeus believes that Kim’s abilities can be useful in searching for the family treasure. The flooded city, the graves of executed revolutionaries and dungeons are deadly dangerous. Salvation comes from... a ghost. And Kim realizes that she fell in love with a man who died a hundred years ago. The heroes are looking for answers in the past, but none of them is ready for the truth that will be heard on the pagan holiday of the Anxious Sabbat.
