Could an explosion on the surface of the sun cause mayhem on Earth? Jason and Jacob are a father-son team from Alabama who are prepping for exactly that: a global solar flare with the potential to wipe out power grids around the world. Jason was almost stranded for good in the wilderness when he was 19, but that will not stop him from prepping in those very same woods by molding his own ammunition and preparing his 20-piece bug-out pack. In Arizona, the Moffatt family teaches their seven children essential survival skills in the event of the collapse of the American economy. In another doomsday scenario, Mike and Grayson are organizing and prepping for the possibility of World War III. While Mike has his Navy training to fall back on, Grayson is hesitant to get away from his pacifist roots.
