There are always some cases in Lin City that appear to be flawless on the surface.
With fake accidents, sealed rooms, and carefully crafted lies, the murderer tried every means to erase traces and disguise the murder as a tragedy.
The Municipal Bureau established a special investigation team four. Captain Lu Zheng is calm and pragmatic and controls the direction of the investigation; Su Wan specializes in criminal psychology and is good at catching subtle flaws in suspects; forensic doctor Lin Xiao relies on objective physical evidence to restore the truth; technician Jiang Chi soaks in surveillance and data to dig out clues that others cannot see.
There is no perfect crime in the world. As long as you commit evil deeds, you will definitely leave traces. The four of them worked side by side to investigate, clearing away layers of fog, using evidence to identify the real culprit, and guarding the bottom line of the law.
