The Doctor Arrives

It’s Christmas Eve and both Rose Tyler’s mum, Jackie Tyler, and boyfriend, Mickey Smith, here the sound of the TARDIS arriving at the London Estate that they live in.

But they are shocked when the craft comes crashing down and then out steps a stranger – who seems to know them both but which they have never met before – before he passes out at their feet.

Luckily Rose appears from the TARDIS and explains that this stranger is in fact The Doctor but he has regenerated to save Rose’s life. The Doctor’s own life is now in danger in more ways the one. Not only is he unconscious and is somehow slipping away but there is an alien presence on the planet that seems to have an interest in his presence.

A Deadly Santa

While Doctor sleeps and is being cared for by Jackie Rose and Mickey go Christmas shopping but are prevented from doing so by a musical band of Santas with guns as their instruments that nearly kill them before they are able to get away. But worse when they return to the flat they are all attacked by a Christmas tree which comes alive. Thankfully The Doctor awakes from his coma long enough to despatch the deadly tree with his screwdriver.

It seems that someone is following them is attracted to them – but why? Could they simply be precursors for an invasion of a much larger force?

The Doctor to the Rescue

Meanwhile, all of Britain is watching television reports on Guinevere One, Britain's newest Mars probe. But unbeknown to them Guinevere One never reaches Mars but instead encounters a massive space-borne craft that is heading towards the Earth.

Soon the whole population is aware of the large spacecraft and the aliens that are onboard. Then when a third of the human race are taken over by the aliens the British Government, lead by Harriet Jones - the new Prime Minister – and UNIT become desperate to find a solution to this invasion.

Soon Harriet Jones finds herself transported to the alien spaceship and joined by Rose – who is in the TARDIS when it to is teleported to the spaceship by the aliens. There they try to convince the Sycorax Leader to release the humans and to leave this planet alone but even Rose, with all her experience of travelling with The Doctor, is powerless to save the planet. It is not until The Doctor awakens – all thanks to a spilled thermos of tea - do events turn to the human’s advantage.

Deadly Santas

After The Doctor challenges the Sycorax leader to a duel, for control of the Earth – which The Doctor wins and so the Sycorax invaders are forced to leave the Earth and never return.

However, despite the departure of the Sycorax’s spaceship Harriet Jones still gives the go ahead to use a top secret defence project based on alien technology called Torchwood to destroy the parting spaceship.

As the embers of the Sycorax ship rain down on London, The Doctor, Rose, Mickey and Jackie enjoy Christmas dinner, and then The Doctor and Rose make their goodbyes... he ready to return to the great unknown out in space, and she now convinced that even with a different face and a different demeanour, he's still the same old Doctor she knows and loves.
