Taizan Muto (Kenichi Endo), who is about to retire, once again ascended to the throne of Prime Minister at the request of the faction boss Futaki Masaichi (Ittoku Kishibe).However, at this moment, another soul exchange event occurred!The souls of the new secretary Saejima Yuka (Ano) and Muto Taizan have been exchanged!According to the investigation of Nitta Ri (Yamauchi Keiya) and Nekota (Yamatoki Satoma), the target of this exchange is [all citizens] - just like this, Taishan was once again involved in an unprecedented terrorist incident, one after another.Change events will follow!?

Taishan, who had a headache in the Prime Minister's Office, came to his senses and found himself standing in a certain mountain, holding a shovel.In front of me was a man with his hands tied, his face covered in blood, and he fell slumped to the ground - “ Could it be that I was exchanged with the murderer!?”Taishan found himself surrounded by men with sinister faces, threw down his shovel, and ran away!

At this time, Kinoshita Naoki (Soda Ryosuke), who exchanged with Taishan, is staying at the countermeasures headquarters for the stand-in incident with Kariya Koji (Kaneda Akio), Tanaka Maruichirota (Ohashi Kazuya), Yuka and others.Tanaka Maru and others never thought that Taishan in front of them had changed his soul. No matter what he said, he only answered “ah...”. Taishan and others were so worried...?

On the other hand, Tarzan (Kinoshita-face), who escaped from his pursuers, ran towards the mansion with no money and no contact information!
