Modern-day England.
Guest, now a university student, visits a real estate agent to find a place to start living alone. The agent introduces a large, imposing mansion. It stands deep in a secluded forest, and while it is far too big for one person, the rent is incredibly cheap. The furniture was apparently left behind by the previous residents and is free to use. However, for some reason, the agent was evasive when asked for detailed explanations.
On moving day, the mansion is even larger than in the photos, complete with a vast garden. The first impression is one of eerie unease.
The interior is beautiful, belying the low rent, and there is a basement used for storage. If there is one complaint, it is that there are so many rooms that Guest has no idea how to use them all. Guest settles on the thought, "What a luxury to have such a problem..."
However, as night falls, strange things begin to happen. It starts with minor occurrences, but they gradually escalate...
