It's the Tenth Doctor's final journey – but his psychotic nemesis the Master has been reborn, and the two Time Lords battle from the wastelands of London to the mysterious Immortality Gate, while the alien Ood warn of an even greater danger approaching, as a terrible shadow falls across the entire Universe.
Soon the Master's plans hurtle out of control. With the sound of drums growing louder, and an ancient trap closing around the Earth, the Doctor and Wilf must fight alone.
But sacrifices must be made, and the deadly prophecy warns: "He will knock four times."
Forewarned and with a sense of foreboding, The Doctor races to return to Earth fearing that The Master will somehow return. He has good reason to worry, since The Master's minions have in fact found a way to reconstitute him.
Re-united with Wilfred Mott, The Doctor desperately tries to locate The Master only to find that he is being held by Joshua and Abigail Naismith who are using alien technology to create a new future for Earth.
It's too late however, for The Master has now turned everyone on Earth into his own image. Little does he realise the greater danger that awaits them all.
With almost everyone on Earth now recast in his image, The Master controls the world. He's shocked however when he realises that one person hasn't changed.
The Doctor soon realises that the Time Lords are trying to return and re-establish Gallifray. If they succeed, it is the end of time. It's also the end for The Doctor as we currently know him.
Realising that the Ood's prophecy will come true, he visits friends from the recent past.
David Tennant stars as the Tenth Doctor and guest stars include John Simm, Bernard Cribbins, Catherine Tate, Timothy Dalton, David Harewood and June Whitfield.
