While babysitting one night, a girl photographs her niece in an otherwise empty house. Strangely, the picture seems to indicate the contrary, revealing the presence of an unforeseen visitor lurking in the background. She has the face of an older woman, closely resembling the great grandmother of the babysitter. Is this woman a guardian angel, keeping a watchful eye over her beloved family? Or perhaps she has a simpler agenda, just wanting to be included in one last family photo.
