Chen Qing sells counterfeit identity chips on the black market, just to survive in the corroded underworld.
In an ordinary transaction, he received an old banknote with a strange number printed on it.
That number belonged to the city official who turned his mother away three years ago, causing her death.
Following the clues, he stepped into the officially declared "abandoned" North District and discovered cages, silent witnesses, and an iron door leading to deeper darkness.
Here, the operation of the glamorous city secretly depends on a conveyor belt that swallows up "useless people".
When he grasped the rusty key that could unlock the secret, he also became the next target to be eliminated above the prison.
