In a fast-paced modern metropolis, screenwriter He Yuanzhou started writing a column called "Urban Imagination". While collecting anecdotes, he discovered that there are more and more events in reality that are beyond reality and common sense. Many protagonists are involved in it due to society, family, dreams and accidents: surreal urban legends, underground thought experiments, strange network phenomena, technological illusions and psychological puzzles are intertwined. Everyone is exploring the truth and trying to break the boundaries of their own thinking. Multiple story lines run in parallel, human nature and imagination contrast with each other, and finally converge in a huge urban mystery, questioning the boundaries between reality, fiction and the human heart.
