Kate Dibiasky (Jennifer Lawrence), an astronomy grad student, and her professor Dr. Randall Mindy (Leonardo DiCaprio) 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 (Rob Morgan), Kate and Randall embark on a media tour that takes them from the office of an indifferent President Orlean (Meryl Streep) and her sycophantic son and Chief of Staff, Jason (Jonah Hill), to the airwaves of The Daily Rip, an upbeat morning show hosted by Brie (Cate Blanchett) and Jack (Tyler Perry).
