The episode starts off with America announcing the start of the World Conference. He asks for the other countries' opinions, but then disregards that and continues talking very fast. He then proposes a plan to create a huge hero to protect the Earth from global warming. He then declares that no one is allowed to disagree with him. Japan then agrees with America only to have Switzerland angry with him for not speaking about his own opinion.
England speaks gentlemanly and says that he disagrees with the unrealistic plan. France interrupts him and says that he disagrees with both England and America. England and France start fighting, so China offers them some snacks to calm them down only to be rejected. Spain then asks Russia if he will try to break up the fighting. Russia responds that he just wants to see Lithuania get in trouble and cry to him for help. Then he asks Latvia if he agrees, and Latvia nods because he has no choice in the matter as Belarus is pointing a knife at him.
Estonia then tells Russia that it's not nice to pick on weak countries. Russia ignores him. Poland randomly pops in and defends Lithuania threatening to "whip out the Poland rule and make Warsaw your capital" on Russia. Greece falls asleep during the meeting as the fighting escalates. Germany has had enough at this point and orders everyone to stop. The fighting stops and the meeting appears to continue normally, but that is ruined as Italy gleefully shouts, "PASTAAAAAA!"
It is now WW1. Germany crosses a border with only a stick, but is anxious because he feels that he should meet a descendant of the great and powerful Rome at this time. However, all he finds is a box of tomatoes. The episode then starts the "Chibitalia" segment. It tells the story of young Italy when he was separated from his older brothers and lived with his grandfather, Rome, for a while.
Young Italy is able to see his older brothers again, but when he could, they had all turned into jerks... Young Italy then runs away from Holy Roman Empire who demands that Chibitalia becomes a part of his empire.
