What I Have Gotten Myself Into

Does anyone have any ideas for a play I must write for English? It should include

A)Two teenagers are sent into a book via tornado/lighting/something else wacky and
B)Wind up in the Middle Ages (including fictional elements such as dragons, of course, if need be) where they
C)Encounter a maiden and her klutzy knight. I must also make it
D)Interesting (corniness optional)

Only I have to write such a story in a day tomorrow and I was hoping someone would have am idea to help me. It doesn't have to be and idea that encompasses the all the above, but, frankly, I need help >_<

Thank you!
