With a new weight-loss pill tested in London by Adipose Industries, The Doctor goes to investigate the sinister truth behind the product, only to find out that his old friend Donna Noble is investigating as well.
The Doctor and Donna join a group of archaeologists at a 51st century library. What caused the library to become abandoned? What are the Nodes? And what links the library to one little girl? All they have is one warning - count the shadows.

In the wake of Davros' threat to destroy the existence of the Universe itself, the Doctor's companions unite to stop the Dalek empire. Which one will die by the prophecies and what will the fate be for the Doctor?
