"Trace of Traces" is a criminal investigation suspense series with modern forensic science as its core, focusing on a professional, calm, and closely coordinated forensic team. Members include Chen Feng, a forensic expert with strict logic, Ling Fei, a forensic doctor with keen intuition, Gao Jian, the action criminal police captain, and Li Ming, a digital forensics expert. They use cutting-edge science and technology combined with traditional investigative methods to peel off trivial traces and solve bizarre murder cases - from secret room murders and digital crimes to old unsolved cases and perfectly disguised scenes.
However, after cracking countless cases, Chen Feng, the core of the team, discovered a subtle clue that actually connected multiple current cases with an unsolved "ghost" case that had not been solved for many years. As the investigation deepens, they realize that their opponent is not an ordinary criminal, but a very intelligent and threatening existence hiding in the deeper darkness. The "Shadow" seems to have already penetrated into their investigation operations, and can even manipulate crimes, eliminate witnesses, and directly provoke the police.
From then on, "Micro Traces" not only solved the unit case, but also gradually revealed a dark thread that runs throughout. The team must face prying eyes and manipulation from the dark while solving the case. Between science and intuition, evidence and conspiracy, they must pursue a real opponent who has never been caught. This is the ultimate battle about justice, trust and obsession.
