The final 2022 special celebrating the 100th anniversary of the BBC in which Jodie Whittaker stars as the legendary Time Lord for the last time. When the Doctor learns of a Dalek plot to destroy the world, she realises that they have allied with the Cybermen at the behest of the Master (Sacha Dhawan) and have enslaved an energy being which they plan to use to trigger all the volcanoes on Earth to erupt at once. With the help of current and former companions including Yaz (Mandip Gill), Tegan Jovanka (Janet Fielding) and Ace (Sophie Aldred), the Thirteenth Doctor faces her final battle before she regenerates once more.
