Set in Los Alamos, New Mexico, 1945. The Second World War is coming to its bloody conclusion, and in the American desert the race is on to build an atomic bomb. The fate of the world is at stake in more ways than one. Someone, or something, is trying to alter the course of history at this most delicate point. And destroy the human race.

The TARDIS takes the Doctor and Rose to a destination in deep space - Justicia, a prison camp stretched over seven planets, where Earth colonies deal with their criminals. While Rose finds herself locked up in a teenage borstal, the Doctor is trapped in a scientific labor camp.

In 1920s London, the Doctor and Rose find themselves caught up in the hunt for a mysterious murderer. But not everyone or everything is what they seem. Secrets lie behind locked doors and inhuman killers roam the streets. Who is the Painted Lady and why is she so interested in the Doctor? And can anyone be trusted to tell the truth?

On another world, an alien war is raging. The Quevvils need to find a new means of attacking the ruthless Mantodeans. Searching the galaxy for cunning, warlike but gullible allies, they find the ideal soldiers - on Earth. Will Rose be able to save her family and friends from the alien threat? And can the Doctor play the game to the end - and win?

The Doctor walked slowly forward into the cul-de-sac. The giant dinosaur turned its head to focus on the midget now approaching. The Doctor aimed his gun to fire. Suddenly from behind came a great roar of anger. He spun round - blocking the exit from the narrow street towered a Tyrannosaurus rex, its savage jaws dripping with blood.
