The Thirteenth Doctor has taken Yaz and Dan to see a pantomime production of Cinderella. However, Dan is not having fun, and with all his complaints, the Doctor decides to go off to arrange something special during the intermission. To Dan's disappointment, it's not ice cream — instead, after the Doctor returns, the second half of the show takes a surprising turn as the actors in dodgy costumes are replaced by the real article. Unfortunately, the real Demon King and his servants are not sticking to the plot and instead begin attacking the audience, as does the animate giant pumpkin which replaces the pumpkin carriage prop.
