Unsolved cases, missing evidence, lost situations are all difficulties that the forensic team has to face. Although they will encounter dangers in the process, they will stick to their original aspirations, start over again after falling, and will not give up on the pursuit of truth. The case and the layout of "Steel Evidence V" are even more surprising, just rely on "Forensic Team", "Forensic Team" and "Crime Team", the iron triangle of crime fighting, they work together, find the real culprit, justice for the survivors, and justice for the dead.
