An American team of paranormal investigators with their own TV show head for the idyllic highlands of Fraser's Hill, Malaysia, to gather evidence at a house built in the 70s. The homeowners claim to have experienced strange disturbances. At first, the couple's claims seem dubious and the investigative team suspects the two may just be publicity seekers. But Jules, the team psychic, soon has her own horrifying experience in the basement, leading them to believe there might be more than meets the eye. As the crew delves deeper into the mystery, they encounter terrifying possessions and apparitions, discover secret rooms, and uncover darker secrets within the history of the house with its connections to an ancient forbidden Thai ritual, stillborn babies, restless female spirits, and a violent supernatural force that threatens to destroy all who come into contact with it.
