The Doctor's own people - the Time Lords - have foreseen a time in which the Daleks dominate all other lifeforms in the universe. So disturbing is this possibility, that they break their own Laws of Time in an attempt to change the future. And who better to send on this quest than their own renegade number - the Doctor.

Unwillingly transported into the fields and trenches of a battle-exhausted Skaro, the Doctor must face his most dangerous mission ever - to prevent the Daleks from ever being created.
