Romana’s proud new Gallifrey is falling – the Daleks have come through the Axis from one universe, preparing to conquer all others. Swarming through the corridors of the Capitol, the Daleks seek, locate and exterminate everyone they find – because they are searching for something, a something they believe will give them domination over the entirety of existence. And it can only be found on this particular Gallifrey.

Whatever happens, wherever Romana, Leela and Narvin go, the Daleks will pursue them until they have what they want.

But elsewhere, someone else in another reality has a plan of their own, and is waiting for the right moment to confront Romana. Is this salvation or the ultimate betrayal?
