In a forgotten small county town - Bisi, now named Sahe, there is no river, only decay and silence shrouding the dilapidated streets. The prosperity of the past has become a thing of the past. The people in the town sneered at the name change brought about by the new mayor, but no one dared to speak out. Shengzi, a little girl struggling between reality and illusion, lives with her grandmother in this rundown town. Grandma, that seemingly loving old man, hides a dark and bloody secret - she was once the most cold-blooded killer in Bisi, specifically responsible for eliminating "outsiders" from Baoxin, the prosperous city next door.
Now, the son must uncover the truth hidden by his grandma, find his own identity, decipher the conspiracy behind this town, and even face forces that may not be human - in this city that has long been swallowed up by time and evil, who is the ultimate prey, and who can escape this fateful killing?
Concept: The story explores how people search for truth and self in a decaying environment, revealing the dislocation of memory and reality, the complex emotions between generations, and the pursuit of identity and belonging. In this land of constant decay, the experience of giving birth symbolizes how individuals struggle with the constraints of society and their hidden pasts.
