The southwest border port city is a golden channel for drug smuggling. An unknown body floated from the estuary. A small word "shadow" was engraved on the edge of the anchor tattoo on his ankle.
Lu Shen, deputy captain of the Municipal Criminal Investigation Detachment, lost his partner Lin Nan three years ago and has since imprisoned himself in a cage of logic and evidence. Gu Lanzhou, consultant of the anti-drug detachment and a former undercover agent, has the same anchor tattooed on his wrist, and holds in his hand the last words left by Lin Nan. Two men bound by the same dead man are forced to step into the same storm. The deceased was Akai, Lin Nan's informant back then. There was Burmese durian candy in his stomach, cyanobacteria from the sand quarries upstream in his lungs, and the new drug carfentanil was found on his body. Just as the investigation began, the key witness "Old Ghost" was killed in front of Lu Shen's eyes. The fingerprints left on the murder weapon belonged to Lin Nan, who had been cremated three years ago.
The anchor tattoo is the symbol of Yuanzhou Group. The founder Shen Jingtao is a legend in the business world and is also the true identity of the rumored drug lord "Black Buddha". Akai discovered the secret of the "Lanjiang" cargo ship transporting cash. Shen Hao threw him into the shoal, and the "Black Buddha" sent someone to kill him and sink his body. Three years ago, Lin Nan was close to the truth, but the goods were transferred and he was accused of "treason" and silenced. The person who personally signed his death order was today's Shen Jingtao.
When Lu Shen's logical deduction collides with Gu Lanzhou's street intuition, when the earrings with the word "shadow" meet the anchor tattoo, the two scarred people must walk on the edge of trust and suspicion, and fish out from the code of a floating wreck the truth about what sank three years ago, and those who never sank in the darkness.
The anchor did not sink, it just changed the sea.
Intention: Together in the abyss, we anchor the darkness and ferry the light.
