An acclaimed author has developed an interest in satanism and black magic. Hoping to manipulate him to suit his own perverse desire, his publisher convinces him to perform the ultimate black rite: a human sacrifice. Selecting a beautiful burlesque dancer to be their victim, he begins having doubts about his beliefs, as his publisher becomes more and more preoccupied with the black arts, and murder.
