Sarah and her unborn son/daughter are all alone in their house while Ash (the husband and father) is out of the country.
Sarah begins to feel that someone is stalking her in her family's home.
The first night, Sarah starts to hear voices while in bed. She closes the door, turns off the light, and goes back to bed. However, when she's back in bed, two arms grab ahold of her, but then she wakes up, realizing that it was just a dream.
Sarah continues to call Ash, but he never calls back, and begins to hear voices in her head, such as her husband talking and a baby crying.
One night, Sarah is goes up to the entrance door, and sees a tall man in the shadows. She quickly turns on the lights, but then he's gone.
