Over 1600 people have gone mysteriously missing in national parks and forests across the US and a group of friends are about to encounter the thing that's responsible. Brothers Brad and Mike Rayburn along with their friend Dennis Copley are the creators of Ultimate Survival, an amateur survival web series they hope will take them to internet stardom. When Hope, an old friend of Dennis' from film school, reaches out and offers up her family's tiny cabin way off the grid in the Rocky Mountains, they all jump at the opportunity to use the location for an episode. Road trip and campfire bonding ensue and Dennis and Hope spark up an old romance but as they hike deeper into the mountains to film their episode it becomes apparent that there is something following them and it's not going to let them leave.
