City of the Forgotten

City of the Forgotten was the first episode of the first series of the alternate Doctor Who. It introduces another Doctor, who suffers from amnesia and whose incarnation is unknown, although shown to have memories from at least the first three of their incarnations.

It also introduces new antagonists, The Forgotten, and a new companion, July Algrove, although she does not immediately join the TARDIS.

The arc of the Doctor's memories, and who he is, begins in this episode and will continue for the rest of the series.

Synopsis
Young adult July Algrove wakes up suddenly in a medieval village, with no memory of how she arrived. Her only hope seems to lie in a strange old man who calls himself 'the Doctor'.

Plot
July Algrove - a young woman in a leather jacket and jeans, with a violet streak through her black, ponytailed hair - wakes up, and soon realises that she's in a wooden hut, with sunlight filtering in from the outside. She slowly walks outside, and observes rows of shacks or tents like the one she woke up in, with people walking about ahead.
