Many people believe that doomsday will eventually come, ending humans' reign on Earth. This series looks at possible apocalyptic incidents that could cause such a result. The show also explores if it's possible to prepare for the hypothetical situations and if anyone would be able to survive. The imagined developments include massive volcanic eruptions, mega tsunamis, out-of-control fires, and an asteroid hitting near the same location like the one that killed dinosaurs 65 million years ago.
