Summoned back to Gallifrey, the Doctor is framed for the assassination of the Time Lord President. To prove his innocence, he must stand for election himself, uncover the traitor in the Time Lord High Council, fight a hooded killer in a nightmare cyberspace world of his enemy's devising and battle against an old foe now out to destroy the Time Lords: The Master.
