The cult members believe that Nix will return from the dead as a god and bring about a new world order. They enlist the help of a young woman, Dorothea, who possesses psychic abilities that they believe will aid in their goal.
Harry becomes involved with Dorothea and her boyfriend, a former cult member named Butterfield, who seeks to stop Nix's resurrection. Harry uncovers dark secrets about Nix's past and his involvement in black magic and sorcery.
As the cult's plan comes to fruition, Nix is indeed resurrected, but not as the god his followers had hoped for. Instead, he becomes a monstrous demon, intent on destroying all those who stand in his way.
Harry and Butterfield must use their skills and knowledge of magic to stop Nix before he can wreak havoc on the world. Along the way, they encounter other powerful magicians, each with their own agenda and motivations.
Ultimately, Harry is forced to confront Nix in a final showdown that will determine the fate of humanity.
