Three years ago, a failed anti-drug operation caused anti-drug policeman Lu Yan to lose his comrades and face doubts. In order to find out the real drug lord "Mr." Behind the scenes, he voluntarily gave up his identity, assumed the pseudonym "Lu Ye", and infiltrated the largest drug trafficking group on the southern border as a mixed investor. Walking on the edge of a knife, every word is a temptation, every trust is a trap. He has to survive the suspicion of drug lords, the betrayal of his associates, and the misunderstanding of the police. He must not only keep the bottom line and not cross the line, but also pretend to be ruthless without being exposed.
The darker the darkness, the truer the light.
When trust and utilization are intertwined, when friendship and mission conflict, Lu Yan must complete a hunt with life as a bet on the edge of the collapse of human nature——
Within the restricted area, there is no way back; under the poisonous net, only justice cannot be broken.
Purpose: To pay tribute to all the anti-narcotics police who are invisible and face the darkness. They are the light walking in the abyss.
