Plot Summary

Lost in the thick fog of a freezing night, about ten followers of Satan, delirious with ecstasy, glorify Ahriman. The Witch completes the macabre ritual, sacrificing a sixteen-year-old girl to the Lord of Darkness and invites him to come to their Sabbath party. The Goat of Mendes inexplicably and mysteriously appears among them and the Satanists, in a state of frenzied paranoia, surrender to a delirium of insanity. Suddenly, the Holy Inquisitor, accompanied by a group of soldiers, interrupts the satanic ritual, arrests the Witch and tortures her until she confesses that she is a heretic and a follower of Satan.
