An anomaly in time brings the Doctor and Liv to London in the 1960s, where they meet a young lady named Helen Sinclair - desperately trying to make a name for herself in the face of sexism and prejudice.

Whilst the Doctor tried to uncover the secrets of a mysterious artefact, a far deadlier mystery awaits Liv and Helen in the collection of a recently deceased antiquarian.

Because that's where they find the Red Lady. Because if you do, you might not like what you see.
