In Yingtian Mansion during the Yongle period of the Ming Dynasty, there was an unconventional girl Su Qingwu. She came from a family of writers. She was so good at autopsy that she could find clues on corpses that others ignored, so she was nicknamed "The Corpse Whisperer". However, Shen Yanzhi, a newly appointed prosecutor in Yingtian Mansion, is an expert in solving cases, but he has an unknown secret.
A bizarre "shadow puppet claiming life" case brought these two people with very different personalities together unexpectedly. The deceased died in a strange manner, which was exactly the same as the shadow puppet drama circulating on the street, and people were panicked for a while. Su Qingwu relied on his superb autopsy skills to discover that the deceased did not die of an accident; Shen Yanzhi relied on his keen insight to find a breakthrough in the intricate clues.
As the investigation deepens, more bizarre cases follow, such as the "Embroidery Needle Murder Case" and "Mirror Image Double Corpse Case"... There is an unknown conspiracy hidden behind each case, and there seems to be an invisible hand controlling everything. As Su Qingwu and Shen Yanzhi cooperated again and again, they went from mutual suspicion to mutual trust. Not only did they have to face the cunning murderer, but they also had to deal with pressure from all sides. In the process of uncovering the truth, they also gradually discovered that these cases seemed to be inextricably linked to an old case many years ago, and Shen Yanzhi's secret gradually emerged...
