Over the course of five seasons, this film chronicles a young woman's rise to power within a tempestuous all-female office. Employing elements of fantasy, realism, drama and satire, much of the story takes place in the confines of an oppressive looking steel and glass skyscraper owned by a powerful insurance company. Though the office is populated only by women, the place seethes with tension due to office politics and the personal turmoil suffered by the employees, something that the beautiful and outwardly ruthless office supervisor Carabosse does her best to ignore. When the ever business-like Carabosse finally gets promoted, she appoints Agate (the story's true protagonist) as her successor. Power corrupts and it does not take long for the compassionate Agate to transform into a copy of Carabosse.
