The Doctor and Donna land in a frightening position in the far future. While investigating a derelict library, the duo come face to face with the disembodied mind of a little girl, an archaeological team led by a woman from the Doctor's future, and swarms of flesh-eating creatures that are seen only as shadows. Surrounded by every book ever written, the Doctor takes control to keep everyone alive and in the light. But the darkness is moving too fast for him, and the key to their survival could be in the nightmares of a little girl...
