In the future city "New Hangzhou" soaked in neon and acid rain, memories can be edited, backed up, and even stolen. Former police detective Lu Chen left the police force due to a tragic failure and became a private detective specializing in dealing with "data ghosts". He lives with artificial alcohol and nightmares from the past, and his only solace is an old compass in his pocket that never turns on. When a bizarre "memory theft" comes to the door, the victim is a top neuroscientist, who has all his core memories taken away and becomes an "empty shell" of a walking zombie. During the investigation, Lu Chen discovered that the method used by the murderer was exactly the same as the unsolved case that led to the death of his partner and his ruined reputation five years ago. In order to pursue the truth and redeem himself, Lu Chen must dive into the darkest abyss of memory in the city and face the past that he no longer dared to touch. As for the rusty compass in his hand, the pointer has long since failed, just like his chaotic and unreliable memory.
