A series of murders with extremely strange techniques broke the tranquility of the city. The murderer left an unsolvable riddle at the scene after each crime. The police asked the public for help, but no one could help.
A bizarre murder occurred at the door of the archives room, and Shen Yuan, who was addicted to piles of old papers, and Lin Mo, who volunteered as soon as he checked in, were forcibly bundled into "temporary partners".
The two people who distrust each other are forced to fight side by side:
Shen Yuan relied on his sophisticated experience to capture clues from the details of the physical evidence, while Lin Mo sketched a portrait of the murderer from the perspective of criminal psychology.
One is as cold as ice and refuses to get close; the other is as eager as fire and chases after every step.
In the process of solving the mystery, they not only have to compete with highly intelligent criminals, but also face a past full of blood and fog.
And in the darkness, there seemed to be a pair of eyes always watching their every move...
Behind the truth is a deeper mystery.
Can this pair of completely different partners break through their inner demons and seize the only light in the test of life and death?
