A police interrogator questions a man inside an interrogation room. The man claims he inherited a building with studio apartments from a distant relative, so he became the landlord of the building, renting the apartments out to tenants. The Landlord's penthouse apartment is equipped with screens that allow the Landlord to see inside each apartment, which all have hidden cameras. His tenants include divorcee Mr. Wang Ming-kai and his fourth-grade daughter; Ms. Chen Min-hui, an office worker who uses her body for financial gain and advantages in the workplace; Mr. Chang Kuo-sheng, a physical education teacher who enjoys peeping on his neighbors and is infatuated with Ms. Chen; Bo-yan, a geeky college student obsessed with the idea of having superpowers; and a gay couple, Kuo Li and Ling Hu. The Landlord also claims that a mysterious woman named Ying-ru lives in the apartment directly under his penthouse; however, the police interrogator states that there is no record of anyone named Ying-ru having lived there.
