In "The Story & the Engine", the Doctor stops off for a haircut in Lagos, Nigeria, and ends up with a little more than a short back and sides. A mysterious barber (Ariyon Bakare) is on the hunt for stories to power his scheme to topple the gods, and nobody has more memorable tales to share than Gallifrey's most famous export.

The Story and the Engine – from writer Inua Ellams – saw the Doctor (Ncuti Gatwa) encounter a mysterious Barber (Ariyon Bakare) who uses the magic of stories to power the engine of his craft, which is concealed within a seemingly innocuous barber shop.
