In a South Yorkshire city, Ryan Sinclair, Yasmin Khan and Graham O’Brien are about to have their lives changed forever, as a mysterious woman, unable to remember her own name, falls from the night sky. Can they believe a word she says? And can she help solve the strange events taking place across the city?

Action-adventure for all the family, starring Jodie Whittaker, Bradley Walsh, Tosin Cole and Mandip Gill. Guest starring Sharon D Clarke, Johnny Dixon and Samuel Oatley. Written by Chris Chibnall and directed by Jamie Childs.

“Jodie Whittaker makes her debut as the 13th Doctor, who crash lands following an explosive regeneration that has apparently destroyed the Tardis.
