Chased by a huge robot that is trying to kill them with powerful energy bolts from its arms, the Eleventh Doctor, Amy Pond and Rory Williams are trying to confuse the damaged robot with facts and derail its programming. Finally as they are trapped on a rooftop — the Doctor's plan appears to have worked just in time. The robot starts to feel less cross. Peacefully displaying signs of the trivia bug, it dispenses non-stop trivia. With the robot pacified, the three travellers leave.
