The Bells of St John

"The Bells of Saint John" is the sixth episode of the seventh series of the British science fiction television programme Doctor Who. It premiered in the United Kingdom on 30 March 2013 on BBC One; the episode was the first of the second half of the series. It was written by Steven Moffat and directed by Colm McCarthy. The episode marks the third appearance of Jenna-Louise Coleman as Clara Oswald, but her first official appearance as the Eleventh Doctor's new companion. The story focuses on alien time traveller the Doctor (Matt Smith) and his search for Oswald, following two previous encounters with her in different moments of time, both ending in her death. Finding a third version in present-day London, he soon becomes involved in saving her and the rest of Earth from Miss Kizlet (Celia Imrie) and her employer, the Great Intelligence, as they use the world's Wi-Fi to upload people to a datacloud via robots known as Servers, casually referred to as Spoonheads. "The Bells of Saint John" was designed to be an "urban thriller", in that it is taking "something omnipresent in your life and making it sinister". It was watched by 8.44 million viewers in the UK. The episode received generally positive reviews, although several critics felt that the plot and threat were lacking. Plot
