A typical public bathhouse located in Tokyo has long been a familiar gathering place for local students, housewives, and ordinary people. However, due to the aftermath of the bubble economy collapse and recent soaring crude oil prices, the business has fallen into severe financial crisis. To survive, the manager takes a bold step: replacing regular mirrors with one-way mirrors and secretly recording footage from behind, which is then taped and sold through underground channels. While some customers have expressed discomfort upon discovering the covert filming, the bathhouse manages to stay afloat. This release includes scenes where the women's faces are clearly visible.
