Laura and Mari are meeting with a medium in the candlelit living room of their new house. The woman asks them about the reason for their call and the girls put her in context. They then begin to explain to her the paranormal events they have experienced since moving into the house: they hear a hissing sound through electrical appliances, a sound they believe to be coming from a hostile and threatening spirit, as they have already suffered attacks from the entity. The woman listens to them attentively before conducting a séance to contact the spirits and find out what is happening in that place.
