Ten years ago, the "712 Dismemberment Case," which rocked Jiangcheng, led to Judge Lu Zhengting's death by execution. All he left his son, Lu Rang, were four words: "I am innocent."
Ten years later, Lu Rang has become Jiangcheng's youngest prosecutor, nicknamed "Lu the One-Strike." Everyone praises his impartiality and bright future. Only he knows the truth: he put on this uniform not to uphold justice, but to personally dig up the case files that were erased all those years ago.
But when he finally pries open the long-sealed iron cabinet, the first fragment of the truth points to the person he respects most: Zhou Mingyuan, deputy president of the court and his mentor.
His mentor is covering something up, the old case is coming back to life, and the mysterious underground alliance known as "the Ferrymen," which once "settled" countless criminal cases, is slowly emerging from the shadows. They don't kill people, but they can make being alive more painful than death.
Lu Rang set out to clear his father's name, but step by step he discovers that his father's "confession" was a deadly gambit: a death sentence for himself in exchange for his son's life.
This time, he will use the law to win justice for his father and everyone who has been "ferried away."
At the end of the long night, daylight must come.
