Suffering from post-traumatic stress, depression, substance abuse issues and more, a small group of military veterans arrive at Camp Winter Falcon's experimental rehabilitation program looking for a second chance.

But soon the patients of Class 001 discover they have a connection to the site's occult history, to one another, and to dark forces eager to commune with human hosts. What should be a three-week mental health retreat instead becomes a terrifying descent into cosmic horror.

Camp Winter Falcon is haunted by supernatural entities intent on making contact at all costs, and the veterans are not patients at all-they are test subjects for deep-state supernatural research... and the first soldiers enlisted for a new kind of occult warfare.
