Story: Six months after Bill's meeting with the Monks, they have taken control of the Earth. The entire populace has been brainwashed into believing that the Monks have always been on Earth, protecting and shepherding humanity since it first evolved. But their rule is totalitarian, and anyone who disobeys their laws — with infractions ranging from reading comic books to remembering the truth about the Monks — is quickly hauled off to prison by the memory police.

As one of the few people on Earth who can remember life before the Monks, Bill knows that she needs the Doctor's help. Except that she can't find out where he is: the only time Bill ever sees the Doctor is during his regular television broadcasts, propaganda films in which he extols the virtues of the Monks and the joys of obedience. But then Nardole appears at her door, having tracked down the Doctor's location, and the hunt is on...
