In a remote observatory, Dr. Lehman (Emmy winner Christopher Lloyd, Back to the Future), discovers a meteor approximately three times the size of Mount Everest barreling its way towards Earth. His devoted young assistant Imogene O'Neill (Marla Sokoloff, The Practice) feverishly types in the coordinates only to find the previously identified meteor named Kassandra is headed their way. It's only the beginning of their troubles as showers of smaller meteorites begin to lay waste to major cities around the globe.
