Class is a new "young adult" series that'll be a spinoff of Doctor Who.
The series will be set in Coal Hill Academy, a fictional school that has been regularly featured in Doctor Who since its original 1963 serial, and will focus on six of its students and staff members, including Mr. Armitage (Nigel Betts), a minor recurring character from the eighth series of Doctor Who.
The students of Coal Hill Academy all have their own secrets and desires. They have to deal with the stresses of everyday life, including friends, parents, school work, sex, and sorrow, but also the horrors that come from time travel. The Doctor and his time-travelling have made the walls of space and time stretch thin, and monsters beyond imagination are planning to break through and wreak havoc upon the Earth.
Here's a fan made trailer showing some of the episodes where Coal Hill has been included...
