In the flawless "Mirror City", memories can be revised and emotions are considered pathological. The man code-named "Prisoner 734" woke up in a pure white cell and was told that he had committed a felony that shook the foundation of the city, but had no memory of anything. The only things that linger in my mind are a woman's vague smile and the smell of earth after the rain. In order to find "her" and his lost self, he must sneak into the depths of this city constructed of sophisticated lies and fight against the ubiquitous "system" surveillance. He will discover that the most terrifying thing is not the forgotten crime, but the tampered truth, and the chilling secret beneath the perfect appearance of the Mirror City.
