An unknown male corpse floated on the East Bridge in Qinghe County. The coroner who conducted the autopsy here was Lu Que, but a mutilated "Netherworld Debt Book" was obtained from the deceased. The debt book can show the unpaid "debt" between the living and the dead, but it cannot directly point to the real culprit. Every time he turned a page, Lu Que had to pay a corresponding price. A seemingly ordinary drowning case gradually revealed a forged identity, a false name and an old case that had been missing for many years. The name of Lu Que's father, Lu Ping, appeared on the debt book again, and the man who was supposed to have been dead for three years seemed to still be trapped in a well-woven conspiracy. From corpses floating in the river to nameless bones, from secrets in deep houses to brides in red, the scars left by the dead do not lie, but the testimonies hidden by the living have their own purposes. Lu Que must rely on autopsy results, scene traces, household registration documents and witness confessions to restore the truth behind each debt. But he soon discovered that "the father's debt must be paid by the son" was not a rule set by the Netherworld, but a lie made up by someone in order to control life and death. As the debt book was filled page by page, Lu Que's own life span was also decreasing. In order to seek justice for the innocent and to investigate the old cases of the Lu family, he must find the person who really controls the debt book before the deadline. Debts can be collected but not robbed; crimes can be hidden but evidence will not disappear.
