I am Yu Sui. I record the details of each crime from a first-person perspective. As a talented profiler, I met Qi Ze, a senior detective who has been involved in the front line for many years, during the investigation of serial unsolved cases. We followed the scattered clues and made inferences layer by layer, and jointly solved the difficult cases that had been covered up in dust. On the long journey to find the truth side by side, we connected with each other, and finally completed the two-way journey.
