Rose and the Doctor arrive in a neighborhood of London shortly before the 2012 Olympic Games begin. The Doctor and Rose learn that a 12-year-old girl named Chloe Webber is the cause of the disappearances of children; she has the ability to make people vanish by drawing them. The Isolus, an extraterrestrial life form that landed on Earth and can empathize with Chloe’s loneliness, takes possession of her, the Doctor discovers. Finding the Isolus’s pod under freshly poured tar in the street, Rose is able to energize it by tossing it into the Olympic Torch as it passes by, providing the pod with heat and emotional strength, which allows the Isolus to depart Chloe’s body. The demon-like drawing of Chloe’s violent and deceased father comes to life as the missing children reappear, but Chloe’s mother allays her anxieties. The Isolus departs Chloe’s body in peace.
