"Last of the Time Lords" is the thirteenth and final episode of the third series of the revived British science fiction television series Doctor Who. It was broadcast on BBC One on 30 June 2007. It is the last of three episodes that form a linked narrative, following "Utopia" and "The Sound of Drums".

One year after the events of "The Sound of Drums", the Master has conquered the Earth and enslaved its population. He holds the aged Doctor prisoner, and prepares warships for a new Time Lord Empire. Now it is up to Martha Jones to carry out the Doctor's plan and save the universe.

A year after the appearance of the on Earth, humanity is on the verge of extinction. After her escape from the Valiant, Martha has been travelling around the world and avoiding the Master's detection through the use of her perception filter. She has been contacting groups of people to find a special gun created by Torchwood and UNIT that can kill the Master. Martha meets Thomas Milligan, a former doctor who leads her to Professor Docherty. Together they manage to capture a Toclafane. Upon examination they discover the Toclafane are the humans from the far future who took the rocket to Utopia. They were driven insane after discovering that Utopia was a lie. The Master created the Paradox Machine to allow them to return to the past and kill their ancestors while avoiding the grandfather paradox. Martha and Thomas leave to find the last component of the gun, and Docherty provides the Master with Martha's location in exchange for information on her own son.

The Master's forces corner Martha and Thomas, and Martha surrenders but Thomas rushes the Master in a rage and is shot. The Master destroys the gun Martha assembled and takes her back to the Valiant so he can kill her in front of the artificially aged Doctor. The Master readies the launch of the Toclafane fleets to conquer the rest of the universe and demands Martha kneel before him. The Master basks in the glory of the last few moments of the countdown and Martha begins to smile. She reveals that the gun was simply a distraction from the real plan, she had really spent the last year following the Doctor's instructions. Martha has been preparing the surviving humans to concentrate their thoughts on the Doctor upon the completion of the launch countdown. The Doctor has spent the past year psychically integrating himself into the Master's Archangel network, which channels the collective psychic energy of the people to the Doctor. A rejuvenated Doctor overcomes his captivity and forces the Master to cower in defeat.
