trauma. Even before the furniture is brought in, the first scary incident happens. Suddenly she starts to hear a gruesome voice in the house, singing and whispering when she's alone. As the scary incidents start to increase and her fear starts to grow, she is finally convinced that she is not alone in this big, dark house. She seeks help from a befriended priest and contacts her psychiatrist, but no one seems to believe her. Completely alone, unable to get help, she starts to investigate by herself. As the electricity seems to not be working, she starts to search the entire house with a light bulb and finds cages with rats in the attic. She flees in terror that night. Unwilling and too stubborn to leave the house, she starts to investigate about the history of the house and finds out that it once belonged to the church as a boarding house for nuns and novices. Finally the electricians arrive. Before leaving, they mention to her that this house is known as the "Snake’s Hole" and known for its horrible past. She visits a local man, that tells her about a horrible murder case that occurred in this house 50 years ago: they found the bodies of three murdered convent women and two of the novices were missing and never found. As the gruesome voice in the house gets louder and more dreadful, she contacts the priest again, believing there's some entity or ghost. He warns her and tells her to better leave the house at once, but as she has put all her money into the purchase of the house she cannot leave. As she starts to check the walls to find out where the voice comes from, she finds an old hidden, big ventilation system with tunnels that seem to run throughout the building. She can now clearly hear something moving through the ventilation-tunnels. She grabs into one of the ventilation gutters and pulls out a decomposed, human foot! As the mysteries about the murders in the house start to unravel, she finally starts to realise the horrible danger she is in.
