In the 37th year of the end of the century, after the "Eternal Night Catastrophe" that covered the world with nuclear winter, the wasteland city "Grey Harbor" became a hotbed of crime. Fang Yan, a former police academy genius, used his "criminal retrospection eye" golden finger to counterattack from a slum coroner to the most popular criminal expert in the wasteland. With the iron rule of "breaking a case and setting up a monument", he solved a series of murders in the gap between the zombie wave and the gang war, but gradually uncovered the truth of the "Eternal Night Catastrophe" - the so-called natural disaster was actually a man-made disaster planned by the powerful in the old world to continue the bloodline. When Fang Yan dug up key evidence from that year, he was marked as a "clearance target." He teamed up with the mutant female gunner Su Mei and in the process of tracking down the real murderer, he accidentally activated the fire of human civilization in the "Sin Monument" and finally led the survivors to restore order.
