Cassie Hughes throws the best parties. Everyone in Sunnydale knows this. It's one of many things that the people of Sunnydale know.
They know that there are drug-addled gangs of violent criminals that explain the town's startling violent crime rate.
They know that the sky often fills with smoke, smog, cicadas, locusts, blood-red moons, and other things that ruin family picnics.
They know that the nightlife in Sunnydale is surprisingly active, for a small town in Nowhere, California.
They know that the best thing to do is get out while you can, but that most people die where they were born.
Cassie Hughes throws the best parties in Sunnydale, though, and so that's where the students of Sunnydale High are doing on this particular night.
