It’s the most important day in the history of Earth—the dawn of a new age of harmony or the start of its final war. The Doctor must face his most difficult challenge yet: It’s a battle he can’t take sides in and a day when no one must die … Meera Syal, Stephen Moore and Neve McIntosh guest star.
Kate is one UNIT’s top people and the daughter of Brigadier Alistair Gordon Lethbridge-Stewart, the military man who was such a good friend to the Doctor.
