In the dazzling "Mirror City", technology can digitize memories. Death is not the end, but the starting point of becoming a "data ghost". Ling Su, a former elite agent, self-exiled due to an accident three years ago that caused the "data annihilation" of his wife and daughter. He lives with cheap synthetic alcohol all day long. One night, the mysterious woman Ye Tong brought a strange case: she claimed to have received a distress message from her deceased brother Ye Feng - a data ghost that should have been completely eliminated. This seemingly impossible commission dragged Ling Su back into the vortex of conspiracy that he had vowed never to set foot in. He must dive into the sea of data, navigate among the memory fragments that are difficult to distinguish true from false, fight against the overwhelming technology giant "Sky Group", and face the torture of crime and punishment deep in his heart. In the Mirror City, the truth is the most expensive luxury, and every echo may come from hell.
