The Twelfth Doctor, flying solo, lands in idyllic smalltown Americana... but there's something disturbing lurking just beneath the surface, a psychic smile that splits the sky and corrupts the minds of everyone present. As the townsfolk start to fracture and tear one another apart, the town's future may rest on the nightmares of a young boy... and a tear in the time/space continuum! It's not nostalgia if they're really out to get you!
