Isabelle, a young university researcher, is sent to a country manor house in rural Shropshire to verify an ancient artefact that a family has uncovered during the renovation of their home. However, the artefact has a cursed history and it soon becomes apparent that the house holds a dark secret. While Isabelle sets to work verifying the object she becomes the obsession of the owner’s dangerous daughter, Scarlet, and they develop a strange sexual attraction. A chance finding of a 200 year old journal confirms Isabelle’s suspicions that the family are not the only residents of the house and that there is something much darker lurking within its foreboding walls. Uncovering the truth, she finds herself trapped in the clutches of the house’s malevolent occupants.
