On the edge of the modern bustling city, there is an underground river town shrouded in continuous rainy seasons. The sky here is always hung with heavy lead clouds, and the fine raindrops are intertwined like silk threads and fall endlessly, giving the entire town a depressing and mysterious color.
Dark River Town has a unique and complex underground river system. The river meanders in the darkness, seemingly hiding countless unknown secrets. The rotten century-old locust tree by the river, with cracked bark and twisted branches, is like a silent witness to the sins and vicissitudes of the town over the years. The abandoned air-raid shelter has intricate passages that connect all parts of the town, as well as old and new crime scenes.
In the archives room of the police station, the piles of unsolved case files exude an old-fashioned atmosphere. These unsolved cases, like dark clouds, have long shrouded the hearts of small town residents. Behind every case is a broken family and a buried truth.
Against this background, a seemingly ordinary disappearance case, like a pebble thrown into a calm lake, stirred up waves of chaos. It is like a fuse, gradually uncovering the secrets of serial murders that have been hidden for twenty years. Criminal investigation methods in the real world and mysterious supernatural forces will also collide fiercely in this small town, and the truth is still looming in this fog, waiting to be discovered.
