The gods have returned, and they're here to save our world.

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 sceptical. 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 principles are tested to their limits. Which side should he choose to help? And what part will a London schoolgirl named Dorothea Chaplet play in the ensuing chaos?

What price is humankind willing to pay for salvation?

Featuring the First Doctor and Steven, and introducing Dodo, this adventure takes place between The Massacre and The Ark.
