Based on classic TVB mystery dramas such as "Forensic Pioneer" and "Criminal Investigation Files", it creates an original Hong Kong-style criminal investigation story. Inspector Ling Xiaorou of the Crime Unit tracked the suspect with keen intuition and thunderous methods; Qiu Guodong, a senior laboratory technician in the Forensic Department, used precise physical evidence analysis to restore the truth of the case; Liang Peiqing, the chief prosecutor of the Forensic Medicine Department, used a cold scalpel to interpret the last words of the deceased;
The "Iron Triangle" composed of three people divides the work and cooperates at the crime scene: forensics investigates clues, forensic doctors decipher the death code, and the crime team connects clues to find the real culprit. From secret room murders to serial crimes, from urban mysteries to old cases, they use evidence as a blade and legal principles as a shield to tear apart lies and stick to justice in dangerous situations, recreating the intense rhythm and warm undertones of TVB-style criminal investigation.
