In a modern city, multiple unrelated ordinary people intersect due to a series of surreal imaginary events. Weird phenomena such as cracks in reality, time dislocation, overlapping memories, and split personalities occur frequently. Han Zhiyuan witnessed unreasonable spatial distortion in a subway accident, Lin Xiaotong discovered collective insanity among his fans, Jia Yunze tried to trace the essence behind the case, and Qin Zhao wanted to use science to explain urban anomalies. The five main characters have each experienced growth and self-questioning, and in the process of mutual cooperation, betrayal, reconciliation, and pursuit of murderers, they gradually uncover the hidden truth behind the city - the blurred boundaries between human self-awareness and the real world. Many 'imaginations' in the city actually originate from the limits of human nature and the pressure of civilization. In the end, the protagonist is closely connected with the fate of the city, and everyone's choices drive the direction of reality and vision.
