On the border anti-drug battlefield, Qi Huaizhi, captain of the anti-drug detachment, led a team to raid a drug den, but they ran into An Ge, the "backbone of drug dealers" that the police had been tracking for half a year - the unrelated brother Qi An who he had been looking for for three years and thought he had died in the sea of fire.
The friendship that once kept each other warm in the alleys was shattered in the smoke and suspicion. Qi Huaizhi holds the gun of justice, facing Qi An, who is both a brother and a suspect, and is torn between his mission and the past;
Qi'an lurks in the heart of the drug lord, working alone in the darkness. He must not only disguise himself perfectly, but also deliver fatal clues in the tit-for-tat confrontation with Qi Huaizhi.
"I am willing to tear through the darkness and give you peace in your life."
