Bishop is trapped deep inside Montana’s Apex Valley along with his injured wife, a shotgun-wielding stranger named Colbrick, and a sneaking suspicion he’s never rendering it back to Chicago. Stuff no man has noticed before haunt the woods. Strange animal types creep behind pine trees, some of them with flashing reddish colored tags that blink quicker and faster. Large birds mimic the sound of human beings and lord within the sky. Leaf-shaped creatures attack whatever moves and display vivid colours across their glistening backs.

As Bishop and his companions scramble over the Montana wilderness, they find human remains to be and animal carcasses littering the woods. The small town of Elmore is empty, the windows broken and streaked with bloodstream. Trout Bridge-their just way out-is obstructed by abandoned vehicles, none which were inbound.

With the strange animal species closing in, Bishop realizes his group must take a stand. He’s got an idea, and maybe they have got one last shot prior to the invasive varieties spread to all of those other U.S.
