Shengming City is a modern city with rapid economic development. One day, while investigating a bizarre disappearance, reporter Jiang Renye accidentally witnessed a 'reality gap': a part of space suddenly became incomprehensible and violated the rules of the ordinary world. At the same time, psychological counselor Gu Xuyao, programmer Chen Ziyan, police officer Liu Xiuqian, corporate white-collar Zhuang Chenhao and mysterious writer Lu Shaomin will be involved in related "brain hole" incidents by chance. Urban anomalies such as dislocated spaces, unsolved dark webs, time cracks, and logical breakdowns are emerging in various hidden corners of the city. Multiple story lines advance independently, and the characters continue to get closer to the truth in the struggle for urban survival, while also facing challenges to their own cognition and existence. As the boundaries between reality and fantasy gradually blur, the essence behind the 'brain hole' phenomenon gradually emerges—the modern civilization structure of Shengming City is undergoing irreversible folding and reorganization. In the end, everyone needs to face the "cracks" in their hearts and make a choice: return to normalcy, or risk their lives and redefine the definition of reality.
