Night shift security guard Xiao Chen encountered the horrifying truth during early morning surveillance: his neighbor Aunt Zhang, who usually brought him dumplings, was supported by a dark shadow into the corridor. After dawn, she forgot about the roses she regarded as treasures and her son who was far away from home, leaving only an empty shell with a standard smile.
Overnight, people in the community were replaced one after another. The stooped Grandma Li, the programmer who uses the air conditioner every day, and the cursing security captain have all become parasites with human faces. They perfectly replicate the host's words and deeds, but erase all memories with strong emotions; they can accurately capture the fear in your eyes. Once you are discovered to be awake, you will be the next one to be devoured.
The entire community became an airtight hunting ground. Xiao Chen formed a desperate alliance with Xiao Li, a rider hiding in an abandoned inn, and Sister Liu, the proprietress of a convenience store, and walked on a tightrope to survive under the eyes of the puppet. But the parasites are evolving rapidly, and the rules of survival are failing one after another. When all surveillance is their eyes, and the whole world has become their territory, where should the conscious living people escape?
