Natural disasters and a breakdown of civilization have cut off Alaska from the world and destroyed its landscape. Now, as food runs out and the few who remain turn on each other, Travis and his younger sister, Jess, must cross hundreds of miles in search of civilization. The wild lands around them are filled with ravenous animals, desperate survivors pushed to the edge, and people who've learned to shoot first and ask questions never.
Josh and three other campers at Simon Lake are high up on a mountain when an earthquake hits. The rest of the camp is wiped out in a moment - leaving Josh, Derrick, Brooke, and Shannon alone, hundreds of miles from the nearest town, with meager supplies, surrounded by dangerous Alaskan wildlife. After a few days, it’s clear no rescue is coming, and distant military activity in the skies suggests this natural disaster has triggered a political one.
