65 Million Years ago, an asteroid impact caused a cascade of catastrophes that led to the downfall of the dinosaurs, but what would happen if the same size space rock struck near the same spot again? How would modern humans cope with a hailstorm of falling rocks and debris, mega tsunamis, out of control fires, blast-furnace temperatures, and a destroyed ozone layer? In the wake of worldwide destruction, who would survive...and who would perish?

For the first time in human history, a volcanic hyper eruption blows through the surface of the Earth. Explosive shock waves tear apart buildings, molten rock slam into cities, and a deafening sound circles the globe. A bad day for Planet Earth gets worse as volcanic gas blocks out sunlight, food chains collapse, and epic famine threatens the very future of mankind.
