There are places in the world so remote, that if you get lost, you may never be found. Olive, Ted, Knox, Birdie and Silas enter a challenge to survive in the wild, without technology. Their stage? The majestic Blue Mountains. Working as a team, they must read maps, build fires, camp and trek through the most dangerous of terrain, in subzero temperatures. But when the teenagers are split over a decision to climb a dangerous rock, disaster strikes. And in their quest for survival, one of them makes an unforgivable choice. With catastrophic consequences. Nobody is blameless. And they may not all make it home. But those who do, may never forgive each other.
