After being discharged from a psychiatric hospital, Song Qiao moves into a new home hoping for peace. Instead, she finds herself surrounded by hostile neighbors who enforce absurd rules, harass her daily, and push her to the brink of relapse. Her only comfort is an emotional support dog—but when the neighbors steal it and humiliate her, Song Qiao snaps, attacking them in a violent outburst. Things escalate further when they break into her home and kill her dog, triggering a complete mental breakdown. When they try to institutionalize her again, Song Qiao counters with her psychiatric proof—legally untouchable. From that day on, she turns the tables. The neighbors who once tormented her are now trapped in a waking nightmare, as Song Qiao becomes the one they fear most.
