Trainee doctor Martha Jones has her hands full balancing her medical studies with placating her demanding family. So the last thing she needs is to find that the hospital where she works has been transported to the moon, where it's invaded by an overbearing alien police force. There she encounters a patient called John Smith, who seems curiously at ease with the situation…

Martha takes her first trip in the Tardis, all the way back to Elizabethan England. She and the Doctor hear of a series of bizarre deaths and discover that playwright William Shakespeare is being controlled by dangerous witch-like creatures. It seems the time-travelling duo must defeat ancient forces to prevent history from being rewritten.

England, 1913. A schoolteacher called John Smith dreams of adventures in time and space. The Doctor, along with Martha, heads to a boarding school, but what he finds is far from ordinary...

It's 1913, and war comes to England early as the terrifying Family hunt for the Doctor.

“Space - the final frontier. Final because it wants to kill us.” Trapped on a space station with no oxygen, the Doctor, Bill and Nardole are horrified to discover the automated spacesuits keeping them alive are also trying to kill them!

A long time ago, the ninth legion of the Roman army vanished into the mists of Scotland. Bill has a theory about what happened, and the Doctor has a time machine. But when they arrive in ancient Aberdeenshire, what they find is a far greater threat than any army. In a cairn, on a hillside, is a doorway leading to the end of the world.
