Demon Theory 

Following an unnerving phone call from his diabetic mother on Halloween night, Hale and six of his med school classmates return to the house where his sister disappeared years ago – only to find a chilling surprise in store for them. Written as a literary film treatment and littered with pop culture references and footnotes, ‚Demon Theory‘ is a refreshing addition to the ‚intelligent horror‘ genre.
