The movie begins with Micah testing out and playing with his camera. He wishes to film the strange and paranormal things that have been happening in the house. They discuss at length about what it could be and they mention that they called a psychic in to help assess what is happening. The psychic arrives that day and learns from Katie that she has been haunted by a ghostly entity since her youth. The psychic informs the couple that they are being plagued, not by a ghost, but by a demon. He says that no matter where they go the demon will follow as it is haunting Katie herself. The psychic explains that the demon feeds off negative energy, so the couple must do their best not to antagonize it or give it more power by fighting with each other. Micah suggests getting a Ouija board, which the psychic immediately dismisses, saying that communicating with the demon will invite it in.


Micah decides to continue his project by setting up a camera in their bedroom, and every night it captures what happens as they sleep. On the first night, a few footsteps are heard. After this, increasingly strange things occur. The bedroom door moves by itself and the lights turn on in the hallway on their own. Each night, when the incidents occur, a low droning noise is heard on the camera.


One morning, Micah goes around the house with his camera and a microphone and openly asks the demon if he should get a Ouija board. When he plays back the audio on his computer, a low inhuman growl is heard after he asks the question. Katie protests his intentions of getting a board and Micah reluctantly promises not to buy one. Against Katie's wishes, Micah borrows a Ouija board to speak with the demon. He sets it up in the living room but Katie yells at him and they argue and go out for a couple hours before Micah can begin talking with the demon. While they're gone, a strange "wind" blows through the living room and the board begins to spell words on its own and catches on fire. A strange image is burned into the board when Micah and Katie return.
