Series 4 Episode 10
The Doctor is trapped, alone, powerless and terrified, on the planet Midnight, and soon, the knocking on the wall begins. Only a woman called Sky Silvestry seems to know the truth, but as paranoia turns into a witch-hunt, Sky turns the Doctor's greatest strengths against him, and a sacrifice must be made...
  • This is the first ever 'companion-lite' episode. Donna appears only briefly in this episode because it was being filmed at the same time as Turn Left.
