Steve Baxter, a mild-mannered, Manchest pub-crawler is called upon one night to his true destiny as the second Son of God. After a couple of convincing miracles, the world looks to Steve for guidance, but he gives mixed signals: on one hand he calls for a Third Testament to establish a foundation for living in the modern age; on the other, he predicts an imminent Judgement Day. The confusion causes mass mayhem, and Steve's disciples, try to make sense of the conflict while preventing devils, in human form, from undermining his mission.
