Li Jin is the most cold-blooded detective in the execution hall. In the past ten years, he has personally sent 23 serial killers to the death penalty list. He is known as "Living Hell". When he identified the last real culprit in the "dismembered corpse case", he found that the birthmark on the inside of his wrist was exactly the same as that of his brother Lu Jianshuang who disappeared ten years ago. The evidence points to Lu Yishuang as the murderer, but those eyes - cold and hidden with unspeakable pain - are clearly his younger brother who blocked the knife for him and was swallowed up by the fire. A chase turned into a silent confrontation between the two; a case was solved, and the truth buried by the authorities was revealed: the fire was deliberately set.
