Buffy is being stalked by a creature intent on killing her so that it can bring about the end of the world. So, what else is new? The only person who can save her is a Slayer who should have died a long time ago. Confused? Well, so are Buffy and the gang. If that's not weird enough, what's she to make of a backpack full of maggots? How about a herd of rats that overrun the cafeteria just as she's sitting down to eat? Just how much can Buffy take before she gets totally grossed out?
