The Xinji City in 202X appears calm and prosperous on the surface, where technology and desire are intertwined, and everyone is coerced by invisible social algorithms. Gao Fan, an ordinary programmer, inexplicably begins to dream about his multiple destinies in a parallel world; psychiatrist Lu Tianqing comes into contact with a group of new patients with strange behaviors and confused memories; reporter Xing Wei follows a mysterious disappearance case, which involves clues about underground power and mysterious experiments in the city; artist Song Mingyue seems to be able to communicate with the "urban consciousness"; investor Zhou Yihang is eager for emerging brain-computer technology, trying to lead a game between capital and consciousness. Five periods of life are intertwined and guided by the "Urban Brain Project" that is gradually revealed. The boundaries between urban reality and surreality gradually blur, escaping from the ordinary daily life, and facing the abyss of human nature and the dawn of hope. Under the pressure of layers of mystery and multiple choices, everyone faces their own growth, betrayal, redemption, and new boundaries.
