Episode 1: Demons of the Mind
Lady Penelope goes on holiday in 1909 Vienna, immerses herself in the local Zeitgeist, meets Klimt, Schiele, Freud, Jung - and foils the dark designs of her old enemies the Lloigor…
Episode 2: Age of the Captain
Back in the 2010s, Penelope discovers the link between the future of the Torchwood Institute and the past of the Time Agency – and finally gets to meet Captain Jack Harkness!
Episode 3: The Sycorax Situation
Having driven off the Hounds of Tindalos from the streets of Cardiff, Penelope travels with Captain Jack through the Rift, encounters an alien horde - and faces a life-affecting choice.
I've also decided to give a title to each season - a title reflecting the overall theme or "arch" of the season. So, season 1 was First Steps, season 2 was Time Lady... and season 3 will be known as The Web of Time (a phrase which will feature as a Bad Wolf-like meme in each episode, culminating in the final two-parter).
