During the Dajing Dynasty, the work of widowers had always been monopolized by men, and it would be deviant for a woman to get involved. Liu Yiyi was born into a family of writers. She followed her grandfather to learn the art of autopsy since she was a child. She has a pair of keen eyes that can discern the hidden secrets in bones, and a pair of hands that can examine the corpse. Her grandfather was unjustly imprisoned and died with resentment. In order to clear his grievances, Liu Yiyi concealed his identity, disguised himself as a man and worked as a county official. With his superb autopsy skills, he repeatedly found key clues in complicated cases and assisted the upright but unsuccessful county magistrate Shen Yanqiu in solving strange cases.
From the unknown female corpse in the field to the bizarre murder case in the Hou Mansion, from the serial murder case in the city to the secret case involving the court, Liu Yiyi used the corpse as evidence and the bones as words, and worked step by step in the male-dominated prison system. Not only does she have to deal with the treacherous and dangerous nature of the case itself, she also has to avoid the suppression of conservative forces and the jealousy and frame-up of her peers. As the investigation deepened, she discovered that behind her grandfather's unjust case, there was actually a huge whirlpool of power struggle in the court. The autopsy knife in her hand not only wanted to open up the truth about the body, but also cut through the haze that shrouded the Dajing Dynasty.
During the investigation process, Liu Yiyi and Shen Yanqiu went from testing each other to trusting each other, from working together to solve the case to fighting the darkness side by side. As a woman, she broke the secular prejudice and used her strength to win the title of "first-class female widower". In the end, she not only vindicated her grandfather, but also promoted the reform of Dajing's prison system and became a legend of her generation.
