Wu An, the administrator of the city archives, accidentally came into contact with a mysterious black mark while sorting out old case files, and since then gained a strange ability - the ability to exchange memories with others.
His originally ordinary life was completely shattered: a drunken man he met on the subway died inexplicably and the convenience store clerk suffered temporary amnesia. The police listed him as a suspect for investigation, and a sudden mysterious file and a strange APP that issued tasks dragged him into a deeper conspiracy.
The ability to exchange memories is no accident. There are shocking secrets of illegal human experimentation and academic corruption hidden behind it. In the process of tracing the truth, Wu An met Lin Weiwei, a teacher who was also involved in the incident. The two formed an alliance in the crisis, but they continued to encounter assassinations and threats.
As the investigation deepened, a biotechnology company called "New Era" surfaced. The intervention of the police, the prying eyes of mysterious organizations, and the pursuit of unknown forces made Wu An realize that he had already become a key pawn in this battle for memory.
He must uncover the truth about his abilities, find out all the masterminds behind the scenes, and protect himself and the people he cherishes at the junction of memory and reality...
