When the teenage daughter of a religious family transforms from A-student into heroin addict, her parents agree to allow a reality TV crew to stage an intervention and tape her recovery. What they don’t know is that she has been taking drugs to deal with the unnatural, evil feelings growing inside her. When she agrees to rehab, with no drugs to suppress what’s inside, the demon emerges.

Exploring the blurry lines between addiction, possession and mental illness, director Seth Grossman refreshes the horror genre with a grounded, layered story of a young girl’s battle against demonic possession. INNER DEMONS utilizes the reality show format to good effect, opting for minimal but effective special effects contribute to the film’s mood of gnawing dread that the worst is yet to come.
