Initially I thought this was going to be more of a creature type horror story, similar to The Mist. It's not, while they hint of something in the fog it is never explained, all you know is whatever goes in ends up screaming and me ere coming back out. Instead it's more about how a camp full of kids set out to survive and establish a community. The best comparison I could give is a modern day Lord of the Flies meets Hatchet. These kids manage to not only to survive but thrive and do better than most of the adults you will meet along the way.
