In the late autumn of 2008 in Shanghai, Shen Linyuan, a tired migrant worker, took the last bus and saw a face suddenly appearing on the foggy window. A crack in reality was opened, and he passively gained the power of teleportation, able to cross streets, pass through walls, and cross houses in an instant. This talent of breaking the laws of space did not bring salvation, but only dragged him into numerous undercurrents covered by the fireworks in the alley. Old cigarette paper shops, archives, dilapidated houses, and corners of ordinary marketplaces all contain secrets that have passed through the years and the abyss of human nature. When he traveled freely through different spaces, he suddenly realized that the physical body can cross distances, but there is no way to escape the barriers between people's hearts. The so-called freedom of coming and going is, after all, just a long trial about choice, cost and truth.
