Doctor Who: Curse of Peladon

Having assumed the guise of Earth delegates, the Doctor and his assistant Jo attempt to diffuse the political timebomb and to uncover the true identity of the beast of Peladon - which they suspect is something far more sinister than a mere paranormal apparition.

The Doctor is amazed, however, to find among the delegates his old adversaries the Ice Warriors - war-like reptiles from the planet Mars. Could they be behind the goings-on and what they stand to profit from a conflict? The Doctor must use all of his wits to ensure that the warnings of Peladon's High Priest do not come true.
