After returning to Japan from a five-year overseas assignment, Tokio Sakamoto (Kyōzō Nagatsuka) takes up his new post as acting branch manager of the Gotanda branch. Branch manager Yoshiharu Takushi (Gin Maeda) orders Tokio to lay off Marika, Emiko, and new employee Nanoko, who are considered "burdensome office ladies." To gather information, he invites the three women to a bar, but when he discovers their true identities, he is filled with bitterness. He then decides to train them to become independent, and all three of them develop feelings for Tokio.
