The novel tells the story of Gu Boyu, the captain of the Criminal Investigation Brigade, and Shen Jinshen, the newly appointed forensic doctor, who are involved in a series of bizarre cases. They work together to find the truth hidden behind the fog.
"Gu Boyu, you are walking in this vast dark night and have seen the bright flowers of sin blooming in the hearts of countless people. Are you full of disappointment in this world?"
"No, Shen Jinshen, because we are moving forward together. With you in the light, I will not walk with the darkness."
