"Nightmare in Silver" is the twelfth and penultimate episode of the seventh series of the British science fiction television series Doctor Who and was first broadcast on BBC One on 11 May 2013. It was written by Neil Gaiman and directed by Stephen Woolfenden. In the episode, the alien time traveller the Doctor (Matt Smith) and the nanny Clara Oswald (Jenna-Louise Coleman) bring Clara's charges Angie (Eve de Leon Allen) and Artie (Kassius Carey Johnson) to an extraterrestrial theme park, where an army of cyborgs called Cybermen reawaken centuries after their defeat in a war. The Cybermen discover the Doctor, and transform him into a "Cyber-Planner", which creates a split personality fighting for control of the Doctor's body with a game of chess. The episode was the first to feature the Cybermen since the episode "Closing Time" in the previous series. It was watched by 6.64 million viewers in the United Kingdom and received generally positive reviews from critics. Plot The Eleventh Doctor takes Clara and her nanny charges Angie and Artie to an extraterrestrial theme park, after they blackmail her about her trips through time. They find the park is closed down and occupied by a punishment platoon, Webley, the theme park's museum curator, and Porridge, a little person who runs the museum's star attraction - a Mechanical Turk-type chess apparatus with a deactivated Cyberman in place of the Turk. There are a number of these deactivated Cybermen around the park, as they were defeated a thousand years ago. The Doctor convinces the platoon that he is an ambassador working for their missing Emperor, and is allowed to stay. An army of Cybermen that were hiding under the park and slowly upgrading their parts wake up and kidnap Angie and Artie. The Doctor puts Clara in charge of the troops, warning her not to let them destroy the planet while he rescues the children.
