Influenced by horror films dubbed the “New French Extremity”, Inner Demon starts off as a serial killer abduction thriller and finishes up as a supernatural revenge film. Teenager Sam Durelle and her younger sister, Maddy are home alone when a knock at the door leads Sam down the road to terror. Abducted by a serial killer couple, Sam manages to escape and find refuge in an isolated farmhouse only to discover it is home to greater horrors and a malevolent spirit. Trapped in the house, Sam is propelled into a struggle for survival, one that will push her to the limits not only physically and emotionally, but spiritually.
