Twenty people carrying secrets were dragged into the quagmire of ten years ago by the "Bloody Rose Case". Detective Chen Zheng is gritting his teeth to reveal the truth, forensic doctor Song Yuan is digging for clues in the corpse until his hands are shaking, Lu Chuan is using his childhood shadow as a human reasoning machine, Ye Zhixia is using psychology to skin the criminal... There are also dark web live broadcasts and supernatural spells to add chaos to his life. To put it bluntly, it's just a group of madmen fighting in the dark. Whoever can't hold on first will become the next "Bloody Rose" sacrifice - after all, the real murderer may be staring at them and laughing.
Purpose: To use the pursuit of criminal cases as a carrier to explore the game between the truth and human nature - when twenty people with their own secrets are involved in an unsolved case, some are pursuing the truth, while others are sinking due to darkness. In the pull of justice and evil, we ask "Can we stick to our original intention to resist the erosion of the abyss", use the shell of suspense to dissect the complexity of human nature, and convey the belief that "even if we are in the quagmire, the light of pursuing the murderer should not be extinguished."
