It's the first comet to buzz the planet in 65 million years, and everyone seems to be celebrating. Everyone, that is, except Regina Belmont (Catherine Mary Stewart) and her cheerleader sister (Kelli Maroney), two Valley Girls who couldn't care less. But when the ladies discover they're the only people who the comet hasn't vaporized or turned into a zombie, they do what all good Valley Girls do, they go shopping...for a couple of machine guns! Never underestimate two girls from the valley!
