The final three episodes of the BBC's relaunched version of the sci-fi classic, starring David Tennant as the legendary Time Lord, and Billlie Piper as his human sidekick Rose. In 'Fear Her', the time travellers arrive in London in 2012, just in time for the Olympic Games. But in a quiet suburban street, something strange is happening - people are going missing with no explanation. Is there a connection to a strange little girl who never leaves her room, and who spends all her time drawing pictures? In 'Army of Ghosts (Part 1)', the Doctor and Rose pay a visit to see Jackie (Camille Coduri), but are shocked to discover that mankind is now sharing its world with millions of strange spectral figures. As the Doctor investigates the truth about these supposed 'ghosts', he is led to the secretive Torchwood Tower, where he uncovers a plot to harness a rip between the dimensions as an energy source. But the Torchwood operatives face an even greater threat than they realised, as the 'ghosts' are revealed to be the dreaded Cybermen, breaking through from their dimension. In 'Doomsday (Part 2)', Cybermen are the least of the Doctor's worries as the Void Ship in Torchwood's basement is revealed to contain a squad of Daleks. Using captured Time Lord technology, the Daleks prepare their own invasion of Earth, and as the Daleks and the Cybermen battle each other for supremacy, the Doctor works out a way to close the rip between the dimensions. But in order to get it shut, will Rose have to make the ultimate sacrifice?
