Taizan Muto (Kenichi Endo), who served as prime minister nine years ago, is now about to retire and end his political career.He is currently living a leisurely life as a parliamentarian, participating in sauna meetings, sushi meetings, divination meetings and other messy activities.At this time, Masaichi Futaki (Ittoku Kishibe), who leads the largest faction of the Democratic Party, found Muto Taizan.

As the support rate hit a record low of 5%, and subsequent candidates were exposed to scandals such as incest, bribery, and gender discrimination, the Gerakan Party fell into unprecedented difficulties. In order to save the Gerakan Party, Yamada ordered Muto to serve as prime minister again.Under Ermu's persuasion, Muto decided to take over as prime minister again.His subordinate Koji Kariya (Akio Kaneda) and his protégé Maruichiro Tanaka (Kazuya Ohashi) follow him.

In order to find a new first secretary, former secretary Shigehei Kaihara recommended Yuka Saejima (Ano).She is an outstanding talent from Narita Ikuei School and immediately proposed a list of cabinet candidates for the Muto Cabinet.Although Muto appreciated this innovative list that was not bound by political constraints, in the end, cabinet personnel had to follow Futaki's wishes.

The next day, when Muto participated in a live TV program with commentator Hasunuma Kiyohiko (Mannosuke Mitsushima) and others, he suddenly felt a severe headache and lost consciousness!When he woke up, Muto found that he had encountered soul exchange again!Nitta Ri (played by Keiya Yamauchi) and Nekoda (played by Yamatoki Satoma) came to the rescue urgently and told Muto that the incident was caused by a hacker attack!?
