The continuing adventures of The Doctor, an alien time traveler - a Time Lord - from Gallifrey. Together with his companions they travel through time and space in the TARDIS, battling evil where they find it.

The new drama from award-winning YA writer and Class creator Patrick Ness (A Monster Calls), centers around London's Coal Hill Academy, which has been part of the Doctor Who universe since its very start... but this has come at a price. All the time-travelling over the years has caused the very walls of space and time to wear thin. When the school comes under the attack of deadly monsters, four students must form an unlikely alliance to defeat them.
