Shen Zhiwei, a talented girl from a family of widowers, was exterminated because her father was involved in a palace secret case. She narrowly escaped by going out for an autopsy. Carrying a blood feud and family stigma, she uses her superb autopsy skills and keen insight to disguise herself as a man and transform into "Mr. Shen", traveling between state and county prisons. From local conspiracies to court strife, from serial murders to old grievances, she peels off the cocoons and repeatedly solves strange cases, gradually getting closer to the truth about the family's extermination. On the way to pursue justice, she met like-minded partners and sympathetic lovers, and together they fought against the mastermind behind the scenes. In the end, she not only cleared her father's injustice, but also single-handedly promoted the reform of the law and became a light in the darkness.
