The roaring production line suddenly falls silent. Beside an oil-stained employee badge, an unsent distress message fades into the darkness. In the chemical plant at dead of night, a missing female worker, bizarre equipment failures, and management's tight-lipped silence weave an impenetrable web. When investigators venture deeper into the plant, they discover that every gear tells a lie and every employee hides a secret in their eyes. This place produces more than chemical materials: it is also an abyss that swallows the truth. Who is manipulating this deadly game? How many souls are trapped in the fog of this steel jungle? The moment you step into the factory, you and I are both caught in the game.
