Kate Dibiasky, an astronomy grad student, and her professor Dr. Randall Mindy make an astounding discovery of a comet orbiting within the solar system. The problem - it's on a direct collision course with Earth. The other problem? No one really seems to care. Turns out warning mankind about a planet-killer the size of Mount Everest is an inconvenient fact to navigate. With the help of Dr. Oglethorpe, Kate and Randall embark on a media tour that takes them from the office of an indifferent President Orlean to the airwaves of a morning show. With only six months until the comet makes impact, managing the 24-hour news cycle and gaining the attention of the social media obsessed public before it's too late proves shockingly comical.
