Coal Hill School has been a regular site of alien activity since Doctor Who began in 1963, and all those years of time-travel have caused the barriers between time and space to start wearing dangerously thin, and something frightening is waiting on the other side.

This young adult drama is being created by young adult writer Patrick Ness, and will star The Night Manager, Happy Valley and Mr Selfridge actor Katherine Kelly as a Coal Hill teacher.

Students at the iconic Who school are played by exciting new acting talents Greg Austin, Fady Elsayed, Sophie Hopkins and Vivian Oparah.

Doctor Who showrunner Steven Moffat is executive producing the show, and says “Class is dark and scary and right now. I’ve always wondered if there could be a British Buffy – it’s taken the brilliant Patrick Ness to make it happen.”

In typical Who style, the four students have to balance their social lives, school work, sex and sorrow while fighting daily to hold the very fabric of space and time itself together.

Set in contemporary London, Class expands the Doctor Who universe in this sharp, funny and scary new drama for BBC Three and iPlayer.
