The Doctor brings Ace home to Perivale. On a summer Sunday it seems the least lively place in the universe, yet mystery lurks behind the calm facade.

The members of Ace's old gang have gone away, each of them disappeared without trace. Something is killing the domestic pets of Perivale, and unearthly hoofprints scar the baked earth of the recreation ground. What strange force connects all these events?

As Ace herself is transported to a distant planet, it seems that the Doctor may be stepping into a well-prepared trap. Can it be the work of the his old adversary, the Master - and if so, to what end?

The Doctor takes Bill and Nardole back to 2nd century Scotland to learn the fate of the 'lost' Ninth Legion of the Imperial Roman Army. 5,000 soldiers vanished without explanation - how?

The search for the truth leads the Doctor and his friends into a deadly mystery. Who is the Guardian of the Gate? What nightmare creature roams the wildlands, darkening the sky and destroying all in its path? A threat from another dimension has been unleashed on the Earth, and only a terrible sacrifice can put things right...
