Aziz Rafael (Michael Sheen Michael Sheen) is an angel guarding the gates, while Crowley (David Tennant David Tennant) is a fallen demon. The two have lived incognito for thousands of years, and through constant attempts, they have established a mutually beneficial relationship between heaven and hell. Crowley was ordered by Satan to send the baby Antichrist to the monastery in exchange for the newborn of American diplomats. When Antichrist reached the age of 11, it was the end of the world. In order to prevent the world from being destroyed, AziRaphael and Crowley decided to avoid the end of the world by influencing the child's concept of good and evil. After 11 years of hard work, the two men were shocked to find that they had got the wrong guy and that the real antichrist was living in a remote town called Tadfield.
