About the title
Richard, newly remarried, goes to visit his ex-wife in order to see his three children from his previous marriage and, at the same time, introduce them to his new partner, Holly. Upon arriving at the country house, they discover that the lady of the house is nowhere to be found, and the children are behaving very strangely. Despite the vague and troubling circumstances, the couple decides to stay and get to the bottom of things, but the more time they spend with the family, the more they begin to suspect that something bad may have happened to the mother.
