Folklorist Shen Yan, who has the bloodline of the ancient "Destroyer of Illusions", is searching alone for his younger brother who disappeared five years ago to save him in an era when urban ghost stories have been materialized one after another and turned into life-threatening rules. When the red sedan chair symbolizing "ghost marriage" appeared again, and the dead man's neck had the same flower mark from the other side as his brother's, he realized that everything was not accidental. Holding the fragments of his ancestral books, he can seek advice from the ancestors of the Ming Dynasty from a distance; facing the criminal police who only believe in evidence and a society where science is paramount, he must break the rules and get to the core of the conspiracy before the next taboo is triggered. Deep in the old streets where hundreds of ghosts walk at night, between the dilemma of family and the common people, Shen Yan will unveil a crazy ritual that attempts to reconstruct the order of humans and ghosts, and in the flames of saving his loved ones and protecting the present world, he will fulfill the final destiny of the Master of Illusions.
