The last time this Comet came the dinosaurs disappeared.
It is late December but this year the world population has more on its collective mind than the coming holidays. Scientists have forecast the coming of an incredibly intense and powerful Comet. The world is prepared to witness the most significant meteorological event in millions of years. In America, celebrations are planned from coast to coast on a scale that will make New Year's Eve in Times Square and the Fourth of July look pale by comparison. Anticipation is at a fever-pitch. What no one knows, however, is that the last time this Comet came the dinosaurs disappeared. This time it will be much more intense...MGM 2007 [dvd]
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 either 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!
