"The Mouse That Roared" is a play adapted by Christopher Seigel from a book written by Leonard Wibberley. In the story, a very small country called Grand Fenwick, is going bankrupt and needs to find a way to get money. The economy of Grand Fenwick is destroyed when a Californian company makes a cheap knock-off of their wine. They try protesting the Californian company, but that doesn't work. They decide to declare war on the United States, because they know that there is no chance they could win. They also know that when they loose, United States would help them rebuild. Somehow, Grand Fenwick defeats the United States. Now the question arises, what does a small, bankrupt country do when it conquers the United States?
