One day, astronomy professor Randall Mindy and astronomy graduate Kate Dibiasky discover that a comet the size of Mount Everest is on track to hit Earth in six months' time. The two try to sound the alarm on the world's impending doom, but unfortunately, no one seems to care. Unfazed, they go on a media tour with the help of Dr. Oglethorpe. From the office of the President of the United States to the booth of a radio station, they will do anything to get the people to look up.
