For years your team has been working on the development of a shrinking maschine, and now you have finally succeeded. However, upon the very first attempt to shrink a pencil, something went utterly wrong: Instead of the pencil you're the ones who are now sitting on your own desk, reduced to miniature size.
Now the clock is ticking because you have programmed the maschine so it will automatically shut down after 60 minutes. Hence you had better make good use of the time in order to recover your normal size, else you will forever remain in the world of the mites.
