The Doctor is back in an all new Doctor Who episode where he and Clara go to the moon, and it looks like all of mankind is at risk again.

The newest episode of Doctor Who, “Kill the Moon,” will see the Doctor and Clara going on a lunar mission, but something goes wrong and it looks like the Earth is in danger yet again.

The synopsis for the episode reads: “In the near future, the Doctor and Clara find themselves on a space shuttle making a suicide mission to the moon. Crash-landing on the lunar surface, they find a mining base full of corpses, vicious spider-like creatures poised to attack, and a terrible dilemma. When Clara turns to the Doctor for help, she gets the shock of her life.”

Last month we found out that Clara could possibly be leaving before the Christmas special this year, or at the very least there are relatively reliable reports that she might be leaving at Christmas. Is Clara Oswald pulling a Martha Jones and starting to want a normal time travel free life? We’ll have to see!
