New York, 1965. A time of conflict between ideologies, races, generations and genders, when crime runs rife and an unpopular war drags on in a distant land. In the midst of this turmoil, people cry out to their gods. And now, it seems, the gods have answered their call. Walking the slums and tenements of downtown Manhattan, demonstrating extraordinary powers, five strangers are gathering a growing crowd of worshippers.Steven wants to believe in miracles, but the Doctor is more skeptical. What are the strangers' real motives, and why does history make no mention of these events? As New York begins to tear itself apart, the Doctor's non-interventionist principles are tested to their limits.
