Three years after the ending of Swallowing the Sea, the undercurrents of Jianning and Jinhai reappeared. The remnant drug network of Spades K, which had been dormant for ten years, quietly returned with the help of new traceless poisons. A series of strange and sudden deaths swept Jianning. All official clues were blocked, the system was covered up by bugs, and the injustices caused by the ten-year anti-drug investigation were buried deep in the dust.
Shen Yanzhou, a new criminal policeman from Jianning, inherits Jiang Ting's wisdom and Yan Xun's character, bears the unjust case of his father's death in the line of duty, and discovers the dark truth in the sealed old documents; Lu Xun, an undercover elite from Jinhai, falls into the abyss of the border, lurks in the drug den alone with all his wounds, and confronts the endless darkness with his flesh and blood.
Two generations of criminal investigators relay their beliefs, and the twin new generations, one wise and one wise, stand side by side in desperate situations. They faced the shadow of the police force, fought against the systemic malaise, dismantled the cross-border drug network, and achieved two-way redemption amidst self-doubt and bloody obsession.
Qin Chuan is still drifting in the gray gap, getting involved in the drama and messing up the situation casually. He never cleans up his innocence and never corrects himself. He becomes the biggest variable in the overall situation with his posture as a prodigal.
Yan Xuan, Jiang Ting, Bu Zhonghua, and Wu Yu escorted and witnessed the entire process. Three generations of police officers went to the dark side to uncover the shady story of the injustice that had persisted for ten years and eliminate the cancer umbrella that had been entrenched for many years.
The abyss is eternal, the light is everlasting. Even if the darkness lasts forever, there will always be young people who will walk forward with light and stick to it from generation to generation, in exchange for longevity in the world.
Purpose: Focus on the inheritance of criminal investigation beliefs and the self-salvation of the new generation, and interpret the background of public security who stare into the abyss, bear pain, and stick to the light. Darkness can never be eradicated, but justice and fire are passed down from generation to generation. Mortals will go into darkness with their own bodies, and they will eventually be clear in the years.
