Story: In a desperate attempt to save her friends, the Doctor plugs herself into a temporal interface in the Temple of Atropos. The four of them soon find themselves stranded amid "broken time", in the heart of a timestorm that flings them into random, and ever-shifting, points in their own timelines.

Yaz is startled to reappear in her patrol car alongside her satsuma-obsessed partner, as a Weeping Angel stalks her from the mirrors. Dan, feeling that something about the world is off-kilter, goes for a stroll with Di that they've already shared. Vinder is forced to confront a pivotal moment from his career, which tested his personal ethics. But the Doctor is submerged in a memory of which she has no recollection: the first siege of the Temple of Atropos, when the Ravagers and the Flux devastated a much younger universe. Why can't she remember being part of the siege, and what secrets about her past might the visions uncover?
