"Class" - A new eight 45-minute episodes Doctor Who spin off from the acclaimed Young-Adult author, Patrick Ness. Class is a Young-Adult series set in contemporary London. Incredible dangers are breaking through the walls of time and space, and with darkness coming, London is unprotected. With all the action, heart and adrenalin of the best Young-Adult fiction (Buffy the Vampire Slayer, The Hunger Games), this is Coal Hill School and Doctor Who like never seen them before.

Four Coal Hill School students who have hidden secrets and desires, navigate a life of friends, parents, school work, sex, sorrow - and possibly the end of existence. Coal Hill School has been a part of the Doctor Who universe since the very beginning, but that has come at a price. Time travelling over the years has caused the very walls of space and time to become thin. There's something pressing in on the other side, something waiting for its chance to kill everyone and everything, to bring us all into Shadow.

Charlie (Greg Austin), April (Sophie Hopkins), Ram (Fady Elsayed) and Tanya (Vivian Oparah), assisted by their physics teacher Miss Quill (Katherine Kelly), are charged with a great responsibility by the mysterious alien known as the Doctor (Peter Capaldi): guard against the creatures of nightmare that want nothing more than to find a way through to Earth and take it for their own.
