Plot synopsis of the opening sequence

The film begins with a girl bringing in the last boxes into her new home after moving in. However, it is revealed to the audience that there is a disabled (or possibly injured) man in the cellar of the house. As he hears her enter he prepares to go upstairs.

Meanwhile, the girl goes into the kitchen and takes out the kettle and mug from a box before realising that a plant needs to be taken outside. Whilst she does this, the man enters the kitchen and watches her, before leaving again as she returns. Upon coming back inside, the girl realises that the mug has been knocked over. As she thinks about this, she hears the cellar door creak and goes inside to investigate.

In the cellar she discovers a candle-lit desk covered in jars and photos; she decides to turn over one of these photos and realises that its a picture of her taken from many years ago. She retreats in terror before spinning to see the legs of the man at the top of stairs.

The title appears and it is left ambiguous as to what happens to her.
