She remains shut inside her home and separated from her husband and daughter–she speaks to them regularly, but rarely leaves the house. Anna keeps tabs on her neighbors in her New York City neighborhood by watching them out the window through the lens of her camera, but her agoraphobia keeps her from truly interacting with anyone other than through message boards on the computer. Anna watches old movies and ponders about her life and the lives of those around her. When she sees a horrifying event through her camera lens, she immediately calls the police–but they find no evidence of the crime and chalk it up to Anna’s over-active imagination and her movie viewing habits. Anna even begins to second-guess herself, until more and more odd occurrences begin to happen and she can’t deny that there’s something sinister going on.
