A young single mother tucks her little daughter, Bethany, in bed after singing her a soothing lullaby. Soon, sweet Bethany is fast asleep and her mother leaves the sanctuary of the dimly-lit bedroom, when all of a sudden, a familiar female voice starts calling for the child. As the voice calling from downstairs becomes more and more demanding, no one can really tell whether it is the voice of Bethany's mother or that of a tricky impostor. Nevertheless, by now, the voice is already angry, commanding the girl to show up. Ready or not, here comes mummy.
