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. The patients of Class 001 quickly 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.
