In the near future world, "Dream Core Office" is the world's top dream architecture agency, which can customize immersive dreams for customers through neural connection technology. Dream architects build scenes, weave plots, and implant emotions based on customer needs, so that customers can experience the perfection they can't find in reality in their dreams. But recently, a large number of clients have suffered mental breakdowns and fallen into persistent madness after waking up from dreams. Their common description is that a man wearing a bronze mask appeared in the dream. Wherever he went, flowers turned into scorched earth, and paradise became purgatory. Behind this "dream pollution", there is a shocking conspiracy that attempts to extract human primitive fears to create spiritual weapons.
