College Professor Koko Misaki (Hitomi Kuroki) is contacted by the executive of a TV station, Shun Yagisawa (Kanji Ishimaru). Shun Yagisawa is her ex-boyfriend, but they have not seen each other in 20 years.

Shun Yagisawa contacted Koko Misaki, because Taizo Yamashiro (Ikko Furuya) asked him to introduce her to him. Taizo Yamashiro is the leader of the Meisei Party and hopes to retake power in the next election. Taizo Yamashiro wants Koko Misaki to become a minister in his party. Koko Misaki balks at the offer, because she doesn't like politicians.

Several days later, newspapers report that Koko Misaki is now a minister. This was planned by Taizo Yamashiro and Koko Misaki decides to enter politics with her husband's, Nobuaki Misaki's (Takashi Kobayashi) support. Right after she takes office a crisis ensues for her.
