Corinne's life might look perfect on the outside, but after three failed IVF attempts it's her last chance to have a baby. And when she finds a tiny part of a doll house outside her flat, it feels as if it's a sign. But as more pieces begin to turn up, Corinne realises that they are far too familiar. Someone knows about the miniature rocking horse and the little doll with its red velvet dress. Someone has been inside her house... How does the stranger know so much about her life? How long have they been watching? And what are they waiting for...?
