The world is preparing to come to an end according to the Divine Plan recorded in the Nice and Accurate Prophecies of Agnes Nutter, Witch (recorded 1655). Meanwhile, a fussy angel and a fast-living demon have grown fond of living among the earth's mortals for many millennia and are not looking forward to the apocalypse. If Crowley and Aziraphale are going to stop it from happening, they must find and kill the Antichrist.

Andrew Williams is a shy, awkward high school student with a straight 'A' average and a horrifying secret: He was born the Antichrist, the profane incarnation of Lucifer himself. While senior year can be Hell for some teenagers, Andrew unleashes the real thing bringing demonic carnage and the horrors of Satan to gym class and beyond. Now that the legions of the undead have risen, some very unexpected archangels are gathered and on the eve of the Second...

In the beginning and eleven years ago, two immortal beings decide that it might not be time to start an Apocalypse. Having followed the wrong boy for years, Aziraphale and Crowley must now try to locate the whereabouts of the real Antichrist. Perhaps the story of Agnes Nutter and her famous prophecies will hold the answer?
