It's the "Meeting Of The World", and all the nations must come together to solve whatever global problems they can. However, after America starts the conference off on a bizarre note, can the gathered nations even solve the problems they have with each other? After this, it's a leap back in time to WWI...

It's WWI, and Germany, in search of the heir to the legendary Roman Empire, discovers an abandoned tomato crate sitting in the middle of the woods. However, even Germany finds himself unprepared to deal with the strange descendant of Rome.
