In a small Montana town, it takes four minutes for every man, woman and child to die. It isn’t a virus or biological attack, but rather the beginning of a geological event that triggers a chain reaction across the globe with devastating effects. A repeat of an extinction event that occurred millions of years earlier. There is no stopping it. The only way to survive is to stay ahead of it. Tom Foster hasn’t flown in decades, yet, he sets his fear aside for a vacation with his grown sons. When the global catastrophe begins, Tom and his sons are in the safest place they could possibly be … thirty thousand feet above the ground. No matter the sacrifice, keeping his family alive is his number one priority and the only way to do that … is not to land until it is safe. With billions dying on the ground, it’s a race to achieve the impossible because there is no other alternative if they want to live.

They thought it was over ... They thought wrong. Shortly after the methane event that took from them their father and most of the world’s population, brothers, Gabe and Owen Foster embark on a quest to look for survivors and a permanent place to start a new life. The storms have ended and air is safe, to them and the others it is time to look toward the future. However, the future is not stable and the extinction level event has only just begun. With a new threat on the horizon, one that can wipe the rest of humanity from existence, the brothers search for a safe haven grows more complicated and the choices are few. It is a race against the clock to not only find, but get to a place where they can live through the catastrophe coming their way.
