Amid growing racial tensions, Ehrich searches for Kifo, the man who stole his brother's mind and locked it inside an ancient medallion. He poses as a stage magician to draw out Kifo's next target—the commissioner of Demon Watch. In the wings, an army awaits Kifo to accomplish his mission so inter-dimensional soldiers can invade New York.
