Christopher Eccleston's Doctor is wise and funny, cheeky and brave. An alien and a loner (it's difficult keeping up with friends when your day job involves flitting through time and space), his detached logic gives him a vital edge when the world's in danger. But when it comes to human relationships, he can be found wanting. That's why he needs new assistant Rose. Rose (Billie Piper) is a shop-girl from the present day. From the moment they meet, the Doctor and Rose are soulmates. They understand and complement each other. As they travel together through time, encountering new adversaries, the Doctor shows her things beyond imagination. She starts out as an innocent, unfettered by worldly concerns. But she ends up an adventurer who, by the end of the series, can never go home again...

Boom Town - The TARDIS crew take a holiday, but the Doctor encounters an enemy he thought long since dead. A plan to build a nuclear power station in Cardiff City disguises an alien plot to rip the world apart. And when the Doctor dines with monsters, he discovers traps within traps.

Bad Wolf - The Doctor, Rose and Captain Jack have to fight for their lives on board the Game Station. But a far more dangerous threat is lurking, just out of sight. The Doctor realises that the entire Human Race has been blinded to the threat on its doorstep, and Armageddon is fast approaching.

The Parting Of The Ways - Rose Tyler has seen dangers and wonders alongside the Doctor, but now their friendship is put to the test as Earth plunges into an epic war. With the Human Race being slaughtered, the Doctor is forced into terrible action. Will the time travellers ever be re-united?
