Lord of Illusions

In the Mojave Desert in 1982, a man named William Nix, also calling himself "The Puritan", has gathered a cult of disciples in an old house. Nix wields real magic and plans to sacrifice a girl, telling his followers he will save the world and grant them wisdom. A group of former cult members, including Philip Swann and Caspar Quaid, arrive to stop him. In the confrontation, Nix's assistant, Butterfield, escapes. Swann is attacked magically by Nix but the kidnapped girl shoots Nix through the heart with Swann's gun. Swann fastens an ironwork mask over Nix's head in order to "bind" him and his power. Nix dies.
