They Came. They Shopped. They Saved The World!
It's the first comet to buzz the planet in 65 million years, and everyone seems to be celebrating its imminent arrival! Everyone, that is, except for Regina Belmont (Catherine Mary Stewart), and her younger sister Samantha (Kelli Maroney), two valley gals who care more about meteoric fashion trends than celestial phenomena. But upon daybreak, when the girls discover that they're the only residents of Los Angeles whom the comet hasn't disintegrated or turned into a zombie, they... well, they go shopping! But when their day of malling threatens to become a day of the mauling, these two val gals flee with both killer zombies and blood-seeking scientists in hot pursuit!
