A newlywed couple, Matt and Daisy, move into their first home together in Wales to raise their first child. While exploring the house, Daisy finds a box belonging to the previous owner containing dolls. She takes a creepy doll to keep for the baby. Later, when alone, the doll moves from where Daisy left it, frightening her. When Daisy calls Matt, who is away for work, he denies touching the doll. Matt returns home but doubts Daisy's story that the doll moved, instead attributing it to her pregnancy anxiety. Daisy insists she saw the doll move.
