One day, Japanese Prime Minister Taizan Muto and his son Sho are flabbergasted to discover that they have switched bodies. In the interest of national security, the switch must be kept secret, which means Sho must now perform as prime minister. Assisting him in this unfamiliar task are the Chief Cabinet Secretary and the prime minister’s Chief of Staff, who are among those aware of the circumstances. But man-about-town Sho has no understanding of legislative debate or question time, and is repeatedly caught making infantile statements or misreading kanji in the documents he is given. Meanwhile, when Taizan goes to a party as Sho, he gets beaten to a pulp by a romantic rival.
Investigations by the Minister of Defense and the security police conclude that the body switch apparently resulted from a terrorist plot. A brainwave replacement chip had been embedded during treatment of their wisdom teeth. When the Minister of Economy, Trade and Industry holds a drunken press briefing, it comes to light that the METI minister and his son have switched places as well.
Now that he is in close contact with the deceit-filled process of political horse-trading, as well as with the media as it pursues bureaucratic scandals with great relish, Sho’s eyes open to the corruption in politics, and he begins speaking out about what he sees wrong. Taizan, meanwhile, in the course of taking a number of employment exams in Sho’s name, comes to realize that the son he thought was a useless airhead has a great deal more substance than he had believed, and in the ensuing job interviews he finds his eyes opening to contradictions and absurdities in the way businesses operate.
With a state visit by the president of the United States as the turning point, the terrorist switch is resolved and Taizan and Sho return to their original bodies. Once again in his political element, Taizan promptly begins pressing for new measures intended to put the interests of the people first.
