S4 E10: The Doctor is trapped, alone, powerless and terrified, on the leisure planet Midnight. Soon, the knocking on the wall begins. Only a woman called Sky 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.
Starring Lesley Sharp, Rakie Ayola, Billie Piper
