"If you don't dissect the dead in the child's time, it will be in vain; you won't use the knife on the corpse in red."
Lu Mingyuan is a forensic doctor and a "corpse whisperer". He can see the last 7 seconds of memory of the deceased, but cannot feel any emotion. When the scalpel cut open the chest of the bride in red and the wedding vows of the Republic of China rang in his ears, he realized that some corpses should not have been opened in the first place. When scientific instruments begin to measure resentment, and when big data analyzes the behavior patterns of ghosts, he must find the common survival rules for humans and ghosts before the next taboo is triggered.
