The Doctor decides to make a "house call" after his psychic paper receives a message from George, a frightened 8-year-old child, asking his help in getting rid of the monsters in his bedroom. On arrival at a council estate on present-day Earth, the Doctor, Amy, and Rory split up to try to locate the child. The Doctor, taking the guise of a social services worker, finds the right flat, and meets George's father, Alex, while his mother Claire is working a night shift. Through Alex's photo album, the Doctor learns that George has been frightened all his life, fearing many of the sounds and people around the flat and is helped to cope by various habits, including metaphorically placing his fears in his wardrobe.
Meanwhile, Amy and Rory, while taking the lift down, suddenly find themselves in what appears to be an eighteenth-century house, but shortly discover most of the furnishings are wooden props. Other residents of the estate appear in the house, but are caught by life-sized peg dolls that laugh and sing like children, and transform the residents into more dolls. Amy and Rory witness one transformation and try to flee, but Amy is caught and becomes a doll herself, joining the others in chasing Rory.
The Doctor, suspecting that the wardrobe contains the evil George fears, opens it to find its contents are simply clothes and toys, including a doll house. The Doctor suddenly recalls from Alex's photo album that Claire did not appear pregnant in the weeks leading up to George's supposed birth, causing Alex to remember the fact that Claire was unable to have children. The Doctor asserts that George is a Tenza child, an empathic alien who took on the form of Alex and Claire's desired child through a perception filter, and has the ability to literally lock away his fears in the wardrobe. George begins to panic from this revelation and the Doctor and Alex are pulled into the wardrobe, joining Rory in the dollhouse. As the dolls descend on the three, the Doctor calls out to George to face his fears; George is able to open the wardrobe and appears in the dollhouse, but the dolls turn to advance on him. The Doctor realises that George is still frightened that Alex and Claire plan to send him away, having mistakenly interpreted a conversation they had earlier that night; Alex rushes through the dolls to embrace George as his son. They all soon find themselves back at the estate, restored to normal. Claire returns the next morning to find George no longer scared while Alex and the Doctor make him breakfast. After being thanked, the Doctor rejoins his companions to set off for their next adventure.
At the end, a nursery rhyme foreshadowing the Doctor's death is heard, and a screen in the TARDIS displays details of the Doctor's death: the date and time he is to die, and the location of his death.
