Emma is 30, single and frankly desperate. She woke up this morning with nothing to look forward to but another evening of unsuccessful speed-dating. But now she has a new weapon in her quest for Mr Right. And it's made her almost perfect.

Gwen Cooper woke up this morning expecting the unexpected. As usual. She went to work and found a skeleton at a table for two and a colleague in a surprisingly glamorous dress. Perfect.

Ianto Jones woke up this morning with no memory of last night. He went to work, where he caused amusement, suspicion and a little bit of jealousy. Because Ianto Jones woke up this morning in the body of a woman. And he's looking just about perfect.

And Jack Harkness has always had his doubts about Perfection.

Featuring Captain Jack Harkness as played by John Barrowman, with Gwen Cooper, Owen Harper, Toshiko Sato and Ianto Jones as played by Eve Myles, Burn Gorman, Naoki Mori and Gareth David-Lloyd, in the hit series created by Russell T Davies for BBC Television.
