Takano Aki is a homemaker who has built an ordinary yet amply content family life. When she and her family move into a luxurious, high-rise condo with all the latest security advancements, Aki anticipates the start of the kind of family life of which dreams are made. Until, that is, she meets her creepy and scary neighbors. Behind the walls of this ivory tower, life is a social ecosystem dictated by strict rules and decorum of vainglorious housewife residents. There are “compulsory Halloween parties”, “hellishly exorbitant lunches”, “floor discrimination”, and even “strictly enforced proper attire for putting out the trash.” Though farcical and comical at first glance, the housewives’ behavior easily becomes sinister, as Aki begins to discover in unexpected ways. Someone is trying to tear her life and family apart.
