Chen Yan, the 45-year-old head of the serious crime team of the Nancheng City Bureau, was brutally silenced while tracking down the "Ghost Organization". However, his remaining soul accidentally fell into parallel time and space and awakened in the body of the 25-year-old cowardly detective "Chen Yan". In this Jiangcheng in 2028, although technology is prosperous, there are turbulent undercurrents. High-intelligence and traceless cases occur frequently. The shadows behind the crimes have the same origin as the "ghost organization" in the original world.
Possessed of the gift of "photographic memory", Chen Yan can reproduce the details of crime scenes and build three-dimensional crime-solving models, but he also suffers from headaches due to overuse of his gift. From the blank playing cards in the "Mirror Murder Case", to the strange imprints in the "Faceless Man Kidnapping Case", to the future text messages in the "Time Loop Case", he controls the young body with the calmness of an old detective and pursues the murderer step by step in the fog - not only to solve a series of strange cases that highly overlap with ten years of unsolved cases, but also to be wary of factional strife and hidden insiders within the criminal investigation system.
During the investigation, his fate is intertwined with that of four women: vicious-tongued forensic doctor Su Qingyue becomes acquainted with him because of the autopsy; hot-blooded reporter Lin Wanxing follows closely to find his missing father; gentle profiler Xia Zhixia sees through the fatigue of his "old soul"; and sinister lawyer Qin Banruo walks the edge of black and white to hide secrets. Emotions and cases are entangled, trust and crisis coexist. When the "Purification Plan" of the "Ghost Organization" surfaces and the countdown to the bomb in Jiangcheng Square sounds, Chen Yan must unite everyone to fight the organization for the final showdown on the night of the full moon.
The fragments of the parallel world shuttle and the remaining memories in the body of the original owner have laid a deeper foreshadowing for this battle of justice...
