In the spring of 1986, Gao Di Street, Guangzhou. Forensic doctor Shen Mo received a piece of homework paper for primary school students, with seven words crookedly written on it: "Uncle Wang died of homicide. Please help me." The old man who delivered the letter disappeared into the morning mist, leaving only the sentence "Things in the mine are handled by the people in the mine."
Wearing an old top hat and a Shanghai watch on his wrist, Shen Mo chased from the fireworks in the market under the arcade in Guangzhou to the abandoned mine in Tonglu Mountain in Hubei. Twenty years ago, geological team member Wang Deming disappeared during an event. Now that the bones have reappeared, they reveal a deeper secret. A mineral vein, an output value of 300 million yuan, four lives - the truth is like peeling off a cocoon, from jealousy to greed, from arrogance to rage, the seven deadly sins of human nature have been fulfilled one by one in twenty years.
From Guangzhou to Beijing, from Hong Kong to Bangkok, Shen Mo and his partner Jiang Ning worked hard to speak for the voiceless and seek justice for the dead in the dusty years.
There is some justice in this world, twenty years late, but it will eventually come.
