Publisher's summary
Mel, Hebe and Elise find themselves inside a plastic bubble-city in a distant future of humanity where robotic 'Purifiers' police the sickly populace. Purity rules this antiseptic nightmare from her high tower, and with the Doctor as her unwilling new helper, she can finally make everything...perfect.

Part one
Finding themselves in the bubble-like Atrium 10-70 in 2527, Mel and Elise surrender themselves to the Purifier robots and are taken to a holding area in solidified foam whilst the hidden Hebe looks on. Hebe saves Nil from the Purifiers when he is exposed to unfiltered air from the outside world and together they rescue Mel and Elise from an incinerator field before going with them to find Purity.

The Doctor and the TARDIS, for which he cannot find his key, is imprisoned in a temporal stasis void by Purity, who has become a computer tower holding the timelines in place. The Doctor finds Patricia inside of the tower and is given back his key when he agrees to hook her up to the TARDIS's psycho-telemetric circuits to help her maintain control of reality, but Purity uses this to search for an iteration of reality which she deems perfect and unwittingly frees Khavûl, Silkreth and their soldiers.
