Wanneer astronoom Randall Mindy en zijn stagiaire Kate ontdekken dat een komeet over zes maanden een einde zal maken aan het leven op aarde, nemen ze direct contact op met NASA en maken ze een afspraak met de Amerikaanse president. Die kan dit slechte nieuws niet gebruiken in de aanloop naar de verkiezingen en besluit voorlopig geen actie te ondernemen. Samen met ruimtedefensiexpert Dr Oglethorpe besluiten ze hun bevindingen te lekken maar de media, maar dat blijkt niet het verwachte effect te hebben.
