In the future city "Xinjing" where memories can be read and edited, Gao Yuan, the founder of the top technology company "Yongyi", died mysteriously. The official conclusion was that he committed suicide. His estranged daughter Gao Lan didn't believe this and spent a lot of money to hire Lin Jing, the most famous but lonely memory diver in the industry, to delve into the last memory of her father before his death to find the truth. Lin Jing, an expert with a tragic past and wary of memory technology, after diving into Gaoyuan's fragmented and chaotic memory ocean, not only discovered a shocking conspiracy "Chimera Project" that could subvert the entire society, but was also forced to face his long-standing nightmare. This is not only a chase for the murderer, but also an arduous search for humanity, love and redemption on the boundary between reality and illusion.
