The bones cannot speak, but the cracks in the bones contain the last testimony of the deceased.
Forensic doctor Xu Yan is good at uncovering forged murder evidence from old bones and calcified scabs, and he partners with the calm criminal policeman Lu Ze to solve various unresolved cases. The murder methods that appear one after another are strange. The murderer deliberately tampered with the bone evidence and left provocative clues. All the details point to the bone repairer who has disappeared for ten years.
As the case was dug deeper and deeper, Xu Yan accidentally discovered that the traces left by the murderer were highly overlapped with the mysterious disappearance of his aunt ten years ago. On the one hand, there are continuous unit murder cases, and on the other hand, there is the truth about the disappearance of close relatives that has been buried for many years; while chasing the murderers side by side again and again, Xu Yan and Lu Ze gradually trust each other and develop feelings for each other.
When all the obsessions of two generations of murderers surface, the bones will eventually restore all the buried crimes, and the truth that was ten years late will finally come to light.
Purpose: Use forensic bone evidence technology to restore the truth of the case. The heroine sticks to her professionalism while investigating the case of her aunt's disappearance, joins hands with her partner to fight against evil, and gains a two-way relationship while investigating the case side by side.
