In the modern city "Jicheng", a series of bizarre cases of "cognitive disorientation" have occurred one after another. Some citizens have experienced strange phenomena such as confusion of self-perception, confusion of time, and temporary fragmentation of space. While journalist Zhou Wanchuan was tracing the truth, psychiatrist Su Can continued to receive relevant patients, genius IT engineer Cheng Anmo discovered loopholes in the city's brain network, and policewoman Yi Lin took over a disappearance case related to these incidents. As the investigation deepens, the trajectories of the five people intersect, and an urban rift hidden on the boundary between reality and illusion emerges. Some huge hidden force in the city is controlling people's hearts and perceptions of reality. Everyone has to face the deep rifts in their own psychology, family and society, and step by step explore the core of the urban "brain hole" project.
