Mirrors are probably the most dangerous objects in the world.
When Lin Shen's sister disappeared out of thin air in front of the mirror, leaving only "He is in the mirror" written with water stains, his world was completely shattered. The investigation led him to the antique shop owner Su Wan and her ancient ancestral mirror, and also tore open the surface of reality - there lurked a dimension called "Mirror Prison", imprisoning all the abandoned fears and obsessions of mankind.
The reflection in the mirror begins to have an independent consciousness, and the glass curtain wall turns into a trap that swallows life. Lin Shen kept going deep into the abyss of the Mirror Prison in search of his sister, only to discover that his family's dark past had the same origin as this disaster. On July 15th, the boundaries collapsed and the two worlds began to bloody merge. And the only figure that can prevent the destruction of the world may be the self who looks more and more like a monster in the mirror.
When looking in the mirror becomes a life and death test, do you still dare to look at yourself in the mirror?
