Doctor Who: The Pyramid at the End of the World

The Doctor, Bill and Nardole find themselves in the middle of a war-zone, as Chinese, Russian and American forces stand poised to clash. At the centre of the field of battle is a 5,000-year-old pyramid, and while there are many problems with the situation presented, the Doctor is concerned with only one - there was no pyramid there yesterday. With the three opposing forces promising mutually assured destruction, and every clock in the world counting down to Earth's ruin, an offer of help arrives in the form of a message from an alien race. To avoid annihilation, humanity must willingly become slaves for their would-be saviours. Sci-fi drama, starring Peter Capaldi, Pearl Mackie and Matt Lucas
