In the Republic of China era, a faceless corpse case throws the Fog City into an uproar.
Xiao Chen, the young helmsman of the Righteousness Hall; Chen Qiming, a detective in the criminal investigation division; and Feng Tinglan, a newspaper reporter. They come from vastly different worlds, but one unsolved case brings them together.
Sichuan opera face-changing, a fire at the Sanqing troupe, an empty coffin in a mass grave... Every clue points to an old debt from thirty years ago.
Before one lead can run cold, the case becomes a series of crimes.
Poisoning by cold tea, a wealthy merchant dismembered, a military intelligence agent sunk beneath the river.
Beneath the surface of this Fog City, every case is like the fog itself: it seems to disperse, yet its roots run deep.
The underworld and the police, pen and blade: how far they get depends on their own abilities.
