2077, New Shanghai. In this city that has been deeply transformed by "Memory Crystal" technology, memories can be read, stored and even edited. Senior memory examiner Lu Chen, while investigating a bizarre secret room murder case, met the only witness - the artist Ling Shuang, whose memory had been maliciously tampered with and fragmented. The official characterized the case as a technical failure and urged closure, but Lu Chen found traces of human tampering in Ling Shuang's chaotic memory fragments. In order to pursue the buried truth, he had to disobey orders, dive into the abyss of data and lies, and fight against a huge shadow trying to control the "reality". This is not only a hunt for the murderer, but also a torture about human nature, memory and the meaning of existence.
