　　Nothing is more frightening, as the narrator points out, than a ‘time-rich nosy person’. Exhibit A is Ahn Geo-ul (Gyeong Su-jin), who commits herself to social justice causes with terrifying tenacity. After temporarily renting a unit in the Baek-sae Apartment building, she discovers that a loud, hard to locate banging noise occurs from 4am every night, making the residents’ lives an insomniac hell – and so she determines to engage in her own disruption and to find the culprit of this acoustic assault, simultaneously eliminating her eccentric neighbours as suspects, and recruiting them to her cause.
　　Focusing on a woman who is an unstoppable force for good, it is also a plea for community cohesion and solidarity.

　　Un professore di psicologia ormai in pensione si ritira con sua moglie in una casa in campagna piuttosto isolata. Non tanto le quotidiane, irritanti e indesiderate visite dell'unico vicino, che riesce a trasformare in assillante tortura la pacifica vita quotidiana della coppia. Una quotidianità che si popola di incubi con l'apparizione dell'ancora più grassa consorte dell'uomo.
