For forty years, black fog has tightly locked Qinghuai Town.
The construction project came to an end decades ago, and several lives were buried under the files of "construction site accidents." Records were tampered with, reports were withheld, and an airtight protective net was used to cover up all the truth.
When Jiang Xu, a young man, was sorting out his grandmother's belongings, he dug out a pile of incomplete old files and accidentally uncovered the dusty evil in the town.
The road ahead is filled with dangers: reporting letters are intercepted halfway, insiders are threatened, and physical evidence is almost destroyed.
On one side, Jiang Xu and Wen Zhiyu fled thousands of miles, breaking through the pursuit and rushing to other places to submit evidence;
On one side, Lin Yu and Xia Xiaohe stayed in their hometown, desperately guarding witnesses and key physical evidence.
Friendship and love are tempered and grown in desperate situations.
There are no superpowers, no halos from heaven, just the courage of four ordinary people.
The night is long and heavy, with enemies on all sides.
With the meager strength of young people, they fought against the entangled darkness and waited for the ray of light at dawn.
The young man is not afraid of the darkness of the long night, and he holds the fire to illuminate the world.
