Aziraphale and Crowley, representatives of Heaven and Hell respectively, are enjoying their cosy, comfortable lives here on earth - they have taken a liking to humanity and despite ostensibly representing the polar opposites of good and evil, have become firm friends. Their comfortable existence of sushi restaurants and vintage Chateauneuf du Pap is disrupted when Crowley is summoned by two demons, Hastur and Ligur, and presented with a newborn baby, the son of Satan, the Antichrist. Despite the best efforts of the Chattering Order of St Beryl, an order established solely to ensure the successful swap of the Antichrist with the son of an American diplomat, chaos ensues at their maternity ward.

Following the birth however, Armageddon now has a date - the Antichrist’s 11th birthday - when the armies of Heaven and Hell line up against each other and the final judgement will descend upon the human species. Aziraphale and Crowley vow to collaborate to ensure the Antichrist grows up in a way that means he can never decide between Good and Evil. That, they believe, would postpone the end of the world.

They each adopt a role in the Antichrist’s life – Aziraphale as saintly, friar-like Gardener, and Crowley, a devilish Nanny. Their endeavour however is in vain, as they discover to their horror at the child’s eleventh birthday party, when the Hell Hound expected to reach the Antichrist on this fails to appear. They have got the wrong boy.

In the present day, the Hell Hound has indeed reached its Master - the Antichrist - Adam Young, a charismatic 11-year-old who lives in Lower Tadfield, a small Oxfordshire village. Despite being the son of Satan and the harbinger of the Apocalypse, Adam has lived a perfectly normal life as the son of typical English parents, and as a result has no idea of his true powers, and the terrifying Hell Hound has been created as a lovable pup.
