Veteran detective Zhou Lan accidentally reopened an old case of a missing scientist that had been lying dormant for three years. As the investigation deepened, he discovered that the missing scientist Lin Shen had actually developed a "Chen Chen Instrument" that could capture fragments of time. This machine, which was claimed to be able to "predict the future," actually held the hope of clearing his grievance for plagiarizing scientific research results many years ago. The suspect targeted Lin Shen's colleague Gao Yu, but not only were Gao Yu's obstructions on the investigation road, but the mysterious time scientific research organization "Chronos" also surfaced. They were eyeing Guan Chenyi in an attempt to control the time dimension for profit. Zhou Lan endured the pressure to pursue the case, but encountered many dangers. In the afterimages and fragments of time, she discovered that Lin Shen had not completely disappeared, but was trapped in a crack in time. A battle about the justice of scientific research and the order of time and space begins. When the truth is gradually revealed, the conspiracy of plagiarism, the ambition of the organization, and the mystery of time emerge one by one. In the end, although justice brings the crime to justice, Lin Shen disappears forever in the long river of time and space, leaving only Guan Chenyi to seal this bizarre and tragic legend.
