In Xinjing City, emotions are commodities that can be traded, and memories are data that can be erased. Here, the technology giant "Xin Tide Group" whitewashes peace with false happiness, while the bottom of the city is filled with the emptiness and despair left by the betrayal of emotions.
Lin Yao, a former ace "fixer", a private detective who has been emotionally drained by the past. He wanders between the light and shadow of the city, handling the dirtiest commissions with his "golden tongue" that can discern all emotions.
A strange "living dead" case involved him in a conspiracy sweeping the city. A forbidden emotion called "Forgotten River" is spreading like a plague. It can completely delete a person's soul, leaving only a perfect empty shell.
In order to pursue the truth, Lin Yao had to cooperate with the glamorous black market intelligence dealer, confront his former colleagues and comrades, and face the crazy genius who tried to use technology to "purify" all human suffering.
As he approached the core step by step, he discovered that the source of the "voiding" that swallowed everything was closely connected with his dusty past.
In this hollow city, will he embrace the painless nothingness, or re-accept the proof of being a human being that can tear him apart?
