The Aliens Arrive

After showing Rose Tyler the past and the future The Doctor decides that it would be a good idea for their next trip, in the TARDIS, to take her back to her own time and place so that she can call in to see her family and friends.

As Rose leaves the TARDIS she instructs The Doctor not to leave without her safe in the knowledge that only 12 hours have passed since she original left with him. But a shock waits for her and her mother when she returns home as it seems that 12 months have in fact passed and that everyone had thought that she had been murdered. Even her boyfriend Mickey is half happy and half angry with Rose as it would seem that as he was the last person to see her ‘alive’ that he was accused of being her murderer.

Both Rose and The Doctor have a lot of explaining to do. But how do you explain that The Doctor is 900 years old, an alien from another planet, that the TARDIS is a time machine and that Rose has been on a trip of a lifetime to time and places no other human had been to.

Fortunately for them both events takes the pressure off them as a damaged alien spaceship crash lands into the river Thames so sealing off central London and puts the rest of the world on red alert. With the single occupant of the spaceship whisked away under tight security The Doctor becomes suspicious that not all is what it seems and goes off on his own to investigate.

His suspicions are proved correct and that this is just an elaborate hoax. But a hoax put in place by alien visitors who have been on Earth for some time. But even he is not prepared for what he finds when he and Rose are invited to a meeting at Number 10 Downing Street. Instead of meeting the Prime Minister, who it seems has disappeared, they find themselves in the company of The Slitheen who have taken over key positions in the Government and military.

But who are the Slitheen and what do they want with Earth? It’s time for The Doctor to get stuck in - but with the world on a knife edge, and about to fall for the elaborate trap that the Slitheens have put in place, it is up to The Doctor to put a stop to the Slitheen's attempt to destroy the Earth and then sell off the radoactive residue to the highest bidder.

But first The Doctor has to prevent World War Three, gain the trust of Rose's boyfriend Mickey so that he can access UNIT's Top Secret website to launch a missile, protect the only remaining elected member of parliment that has not been taken over by the Slitheen and survive the wrath of Rose’s mother who has become over protective of her daughter and sceptical of The Doctor's ability to protect Rose. All this from a sealed off room within Number 10 Downing Street which has been taken over by the aliens.

The fate of the Earth rests with Mickey's ability to fire the missile. And the fate of The Doctor and Rose rests with the strength of the reinforced room within Number 10 Downing Street - the target of the missile…
