A little boy named Martin (Gabriel Bateman) is seeing a woman in the shadows every time he turns off the lights. He's not the only one who sees her. He learns that his big sister Rebecca (Teresa Palmer) also used to experience the same thing.
She explains that she had a childhood friend named Diana to whom something very bad happened a long time ago. Diana feeds on the fact that everyone fears the dark, which is why she appears whenever the lights go out. Nothing can stop Diana from tormenting the entire family. They get so desperate that they even call in the police, but not even armed authorities can put a stop to Diana.
