Three siblings live on a secluded island known as “brothel island” and run the family business with four prostitutes. The oldest brother Tetsuo (Jiro SATO) manages the brothel but has a brutal and violent personality. The younger brother Tokuta (Takayuki YAMADA) acts as Tetsuo's subordinate, while the younger sister Ibuki (Riisa NAKA) lives in the brothel dealing with a chronic illness. The family hides a cruel past.
The film is written and directed by Jiro SATO, an adaptation from his own 2009 stage play. It has been released in Japan in 2020-21.
