Jiangcheng Criminal Police Captain Zhou Jin is resolute and resolute, and has the highest crime detection rate in the city, but he has a problem - an unsolved case three years ago was shelved due to insufficient evidence. The newly transferred director of the forensic center, Shen Qing, is calm, rational and has top-notch professional abilities. He was the appraiser of key evidence in that case. A serial murder case with strange techniques tied the two people together. Zhou Jin suspected that Shen Qing was hiding something back then, while Shen Qing believed that Zhou Jin relied too much on intuition in handling the case. They must put aside their prejudices and track down the real murderer from clues at the crime scene, in front of the autopsy table, and through countless sleepless nights. From partners who didn't trust each other, to trusting their lives back to back, they pursued the truth on the edge of life and death, and unknowingly entered each other's hearts.
