It’s 2015 and the most ambitious drilling project in history has reached deeper beneath the Earth’s crust than man has ever gone before – but now the ground itself is fighting back.

In the latest episode of the time-travelling drama, written by Chris Chibnall, the Doctor, Amy and Rory arrive in a tiny mining village and find themselves plunged into a battle against a deadly danger from a bygone age.

The Doctor is played by Matt Smith and Amy Pond by Karen Gillan.

Doctor Who is simulcast on the BBC HD channel – the BBC’s high definition channel, available through Freesat, Sky and Virgin Media.
