Doctor Who looks like he’s going on a school trip with a difference in this week's episode In the Forest of Night.
It sees the city of London turned into a sprawling, green blanket of trees and the Doctor, played by Crouch End actor Peter Capaldi, racing to discover a solution before humanity is wiped out altogether.
And it looks like Clara's boyfriend, fellow teacher Danny, gets drawn into the action even more than before as they both try to keep their pupils safe.
BBC Saturday at 8.20pm.
