In a world where nations are personified as humans, Italy has joined Germany and Japan as a member of the Axis Powers. However, he proves to be cowardly, carefree, and lazy--very different from his strong ancient ancestor Rome. Meanwhile, the Allies must deal with their own personal quirks.

Countries are depicted as a mix of truth and stereotype--America loves heroes and fast food, Germany is stern and strict, and France is a romantic. Though its main story line follows WWII, it includes character interactions from throughout history. This is a comedic look at their past and progress.
