But the current Keeper, his powers waning, senses some all-pervading evil about to invade his world. He summons the Doctor to his aid.
To save Traken the Doctor fights the terrifying Melkur — only to find that this new enemy conceals an older and even deadlier foe — one the Doctor has encountered before...
