The patients and staff of a secluded heroin treatment center must do battle with more than their own demons as a mysterious killer begins picking them off one-by-one.

INNER DEMONS follows an ‘Intervention’-style reality show crew that films an episode about a sixteen-year old girl, a former A-student, who is fighting addiction but may in fact be suffering from something even more destructive: demonic possession. The movie is an inquiry into the truth about her – with symptoms that straddle the disturbing and scary intersection between insanity, addiction and true possession.
