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.

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...?

After consultation with Chief Cabinet Secretary Kariya Koji (Kaneda Akio), Tanaka Maruichirota (Ohashi Kazuya) and others, they believed that Baghel's visit to Japan was not coincident with the exchange incident, but had another purpose.However, the exchange incident happened again, and Taizan Muto actually exchanged souls with five-year-old kindergartener Shinta Hayase (Nagisa Yoshimoto)!

As he is about to meet with Baghel, Tarzan transforms into a five-year-old child (Shinta's face).Naturally, he could not attend the summit as a child, so he had no choice but to play with the children in the kindergarten.On the other hand, Shinta (Tazan's face), who inexplicably entered the Prime Minister's body, lived as he pleased, playing horseback riding games with Ichirota and coquettishly asking for hugs from Yuka.

At this time, the Countermeasures Headquarters identified the circulation path of the brain wave chip related to the identity exchange and found that it may be mixed with ym.Tarzan, who feels the limit of living with Shinta's body, decides to leave the kindergarten and head to the meeting site with Bugle...!?

However, at this moment, Taizan Muto exchanged bodies with the dying old lady (Qiu Mitsuko)!

Taishan, who has amazing vitality, finally regained consciousness, but he was unable to move while lying on the hospital bed...

On the other hand, the old lady (Tazan face) who mistook the Prime Minister's Office for “Heaven” was taken to the countermeasures headquarters by Tanaka Maru and others. The old lady told them that her body is currently in very danger!They knew that if the old lady died, Taishan would be in danger, so they hurriedly looked for the old lady's hospital.However, during this period, the old lady disappeared from the countermeasures headquarters!?

The old woman came to the streets to enjoy her freedom and actually worked in a fast food restaurant!Youjia finally found the old lady and tried every possible means to find out where she was hospitalized.But the old lady begged: “I don’t want to lose the freedom I finally got, I just hope that today I can do whatever I like.” She took Yujia with her, ate shaved ice, had fun in the reptile cafe, and enjoyed what she wanted to do.

At this time, the grandmother's husband Shin (Ibu Masato) and son Keisuke are faced with the decision of whether to give Tommy life-extending treatment at Aomori Hospital!

Secretary Saejima Yuka (Ano), a young man working part-time, a five-year-old kindergarten child, and a dying grandmother, Muto Taizan (Endo Kenichi) quickly switches between these various roles.At the same time, the cabinet support rate fluctuates like a roller coaster, and Nitta Ri (Keiya Yamauchi) is gradually approaching the truth about soul exchange!A sterilizer is placed in the living circle of those who have been converted...

And 14-year-old middle school student Hagiwara Akiho (Kurokawa Sōya) walked out of the private room of the Internet cafe where the same sterilizer was placed, and came to Shinjuku early in the morning.He asked the young people gathered on the busy street about the whereabouts of a girl named “Xiaoxue”. When he found a person who looked like “Xiaoxue”, he suddenly felt a headache!

On the other hand, Tarzan was threatened with a deal by opposition lawmaker Jinguji using the Budget Committee as a bargaining chip, but he did not accept it.At this moment, Taishan, who had a headache, suddenly found that he had exchanged bodies with Akiho!

After this exchange, Nekota Mamoru (Yamatoki Satoma) quickly confirmed Tarzan's identity (Akiho's face).After meeting Akiho (the face of Tarzan) at the Countermeasures Headquarters, he asked him to attend the budget committee on his behalf, but Akiho refused to cooperate and shouted: “The country can do anything!I'm going to find Xiaoxue!”In desperation, Akiho (the face of Tarzan) was sent to the Budget Committee, and the real Tarzan (the face of Akiubo) came to Shinjuku to look for Koyuki instead of Akiho.Facing the unfamiliar Japanese used by modern young people, Taishan felt at a loss, and what he saw in front of him shocked him even more!

In addition, Tarzan, who discovers numerous scars on Akiho's body, begins to understand the problems he faces...?
