- 10 years ago an employee at Manpan Corporation, thought to be useless, was demoted to the shomuni (general affairs section 2). That division was considered as "the graveyard for female office ladies," as the ladies were tasked with menial work. Six female employees there including Chinatsu Tsuboi (Esumi Makiko) acted according to what they felt was right and didn't follow the company's outdated views of their roles. The women their eventually saved the company and left. 10 years later, Japan finds itself in a long-term economic depression. Companies like Manpan Corporation are restructuring due to the economic climate.
Shiori Maruyama (Honda Tsubasa) was once a promising pole vault athlete, but now works at Manpan Corporation. She isn't good with her work and can't even answer the phone properly. The company views her as useless. Her co-workers leave derogatory comments about her on Twitter and they don't sit near her at company get-togethers. Then, female employees, who act how they want, appear. They are Madoka Minami (Becky), Reiko Abe (Ando Sakura), Misuzu Kojima (Mori Kanna) and Masuyo Fukuda (Horiuchi Keiko).
One day, Shiori sees a woman being chased by someone. The next day, Shiori sees the same woman at Manpan Corporation. Shiori learns that the woman is legendary Chinatsu Tsuboi. Soon, shomuni (general affairs section 2) is revived.
