Mona verhuist met haar vriendje Robbie, die aan een nieuwe baan mag beginnen, naar een appartement in een oud gebouw. Al snel zijn ze in verwachting van hun eerste kind. Mona wordt echter geplaagd door nachtmerries die erger worden wanneer de pasgeborene van hun buren komt te overlijden. Elke nacht wordt ze door een demon bezocht en Mona gelooft dat het wezen de menselijke wereld via haar ongeboren baby poogt binnen te dringen.
