Takafumi Katayama is a mild-mannered father who escapes the pressures of daily life by joining a mysterious S&M club, where the so-called Queens visit clients in real-life settings. While at first the rough treatment and humiliation he receives from leather-clad women in cafés and restaurants is enjoyable, Takafumi soon realizes that hes opened a door that cannot be closed. Unable to end his relationship with the club, he finds himself pursued by a gang of ruthless dominatrices, each with a very unique talent. Takafumi must either find a way to turn the tables, or walk even further down this dark yet sexy path.
