The synopsis 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.”

Harness has previously written episodes of BBC One crime dramas Wallander and Case Histories, but is new to Doctor Who. The Sweden-based writer is also working on BBC One’s upcoming Jonathan Strange & Mr Norrell adaptation.
