Detective Chief Lu Yanchen lost his wife in a murder and was also brutally killed. When he woke up again, his body was shackled in a white light cell, and a cold broadcast announced that the reverse time trial was about to begin.

The hands that used to hunt down criminals are now stained with blood. Torn between the killing and the pain of conscience, he still persists in pursuing the buried truth behind his wife's murder.
