When he woke up, Anning City became a prison shrouded in strange rules.
Lin Yu, an ordinary programmer, discovered that the "Residents' Survival Code" on the community bulletin board, the "Kitchen Taboo" that suddenly appeared in the kitchen, and the supplementary rules from the "Security Bureau" on his mobile phone... Became the only guide to survival. If you follow the rules, you may encounter the fatal trap of conflicting rules; if you violate the rules, weird knocks on the door, the faceless "Aunt Zhang" behind the peephole, and the sound of marbles rolling in the corridor will follow, dragging people into the abyss.
When the familiar world becomes unrecognizable, neighbors turn into distorted phantoms, and security guards become faceless voyeurs, Lin Yu must struggle to survive within the rules that are difficult to distinguish between true and false. He gradually discovered that these rules did not appear randomly. There seemed to be a "game" hidden behind them that controlled everything, and "players" like him were sacrificing their lives to decipher the ultimate truth of this weird talk about the rules.
