I have to write a 3-page story that has something to do with an epidemic. It could be completely fictional, so the epidemic doesn't necessarily have to be the flu or something normal like that. The story needs to have a moral, rising action, and falling action. I want the protagonist to be a girl named Susie. I can't think of an antagonist. Anyone have any plot ideas?

We recently read Into The WIld, by Jon Krakhauer (sp), in my AP English class. We are now required to do a visual aide project (i.e.- powerpoint, collages, paintings, sculptures, videos, etc.) to illustrate one of the five goals of the novel. They are:
1. The allure of high risk activites on men of a certain age.
2. The charged relationship between father and son.
3. The montastic tendencies of McCandless's trip.
4. Krackhaur's inner exploration of himself.
5. The grip nature has on the American imagination.

Does anyone have any good ideas I could use? I can't paint, and I can sculpt only moderately well. Any help will be much appreciated!
