On October 23, in a feature-length special to mark her last adventure, Jodie Whittaker’s thirteenth Doctor must fight for her very existence, against her deadliest enemies: the Daleks, the Cybermen and her arch-nemesis, the Master in the Doctor Who BBC centenary special, The Power of the Doctor.

A synopsis was released for the special:

Who is attacking a speeding bullet train on the edges of a distant galaxy? Why are seismologists going missing from 21st century Earth? Who is defacing some of history’s most iconic paintings? Why is a Dalek trying to make contact with the Doctor? And just what hold does the mesmeric Rasputin have over Tsar Nicholas in 1916 Russia?

The Doctor faces multiple threats…and a battle to the death
