There is no feature for the ninth new episode of the season, The Satan Pit, in this week's Programme Information releases from the BBC Press Office. The programme copy for the episode, however, located here, has the actual blurb for the episode as follows.
Doctor Who: The Satan Pit Rose battles the murderous Ood and the Doctor finds his every belief being challenged to the core, as the Pit beckons in the concluding part of this two-part story. With the planet threatening to fall into the Black Hole, the Doctor must make the ultimate sacrifice – but can he save the entire universe from the Beast? David Tennant plays the Doctor, Billie Piper plays Rose and Will Thorp plays Toby.
