The Pyramid at the End of the World - Trailers

A 5,000-year-old pyramid stands at the centre of a war zone, where the Chinese, Russian and American armies are about to clash. 
There are many problems with that, but the one that intrigues the Doctor is this: there wasn’t a pyramid there yesterday. 
The Doctor, Bill and Nardole face an alien invasion unlike any other – before conquest can begin, these aliens need the consent of the human race.
