Extremis

"Extremis" is the sixth episode of the tenth series of the British science fiction television series Doctor Who. It was written by Steven Moffat and broadcast on 20 May 2017 on BBC One. "Extremis" received very positive reviews from television critics, with many praising Peter Capaldi's performance and Steven Moffat's script, though some commented on the complexity of the script. The Vatican calls upon the Doctor (Peter Capaldi) to investigate the Veritas, a book whose readers typically kill themselves after reading it. When the Veritas is translated and leaked online, the Doctor must uncover the dark secret that the book holds. It is the first of three loosely connected episodes called "The Monks Trilogy". Plot The Twelfth Doctor remains blind following the events of "Oxygen" and wears his sonic sunglasses to provide a limited form of sight while hiding his condition from Bill. He receives an email entitled Extremis that he views through his glasses. The Doctor is met by the Pope and members of the Holy See to help deal with a recently translated text called the Veritas, that causes readers to end their own lives. The Doctor takes Bill and Nardole to a secret library inside the Vatican. They find that a translation of the Veritas has been emailed to CERN. Bill and Nardole discover a portal leading to a hub of other portals, linked to CERN and the White House, among other places. Meanwhile, the Doctor temporarily regains his sight using Time Lord technology and tries to read Veritas, but is forced to flee into a second portal with the translation when the skeletal, corpse-like Monks appear. He is unable to read the Veritas before again losing his sight.
