The UK satellite TV channel Watch will be airing five back to back episodes of the David Tennant era of Doctor Who this afternoon from 2pm.
The schedule is as follows:
2:00pm The Doctor's Daughter
The Doctor meets the most important woman of his life on the distant planet Messaline, in the middle of an endless war. And as General Cobb threatens genocide, Martha is kidnapped by the Hath, but the Doctor faces an even greater battle - can he find peace with his own child?
3:00pm The Unicorn And The Wasp
In 1926, Agatha Christie disappeared for 10 days. Was it amnesia? A nervous breakdown? Or a Giant Alien Wasp..? The Doctor and Donna join forces with the world's most famous crime novelist to encounter a body in the library, poisoned cocktails and a Vespiform seeking revenge.
4:00pm Silence In The Library
One hundred years ago, the Universe's greatest Library was sealed off with only a cryptic warning as explanation: "Count the shadows." However, it now appears that the shadows are on the move again, and the Doctor and Donna must uncover the terrible truth behind the Nodes and the horrifying Data Ghost to uncover the Library's haunting secret.
5:00pm Forest Of The Dead
As the shadows rise and march, the Doctor forges an alliance with the mysterious River Song. But can anyone stop the Vashta Nerada? While the Doctor discovers long-buried secrets, and revelations about his own future, the sinister Nodes declare that Donna Noble is doomed.
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...
