S1, E1: In Discworld, it’s the night before Hogswatch. You know, that special night when the Hogfather delivers presents to the kiddies at the Hogswatch mid-winter festival in the medieval melting pot of Ankh-Morpork. What the Hogfather doesn't realize is that he's being watched by the Auditors—the Discworld’s grey-robed specters who audit not money but the entire universe and maintain the neat order of things. They think human beings are ridiculous; that they are ruining the perfect universe with their willful fantasies—fantasies that make humans, well... human. Now they’ve formulated a plan to destroy human belief so that there's not an atom of it left and the Discworld can finally be theirs.
