There's a part of the city that no one much goes to, a collection of rundown old houses and gloomy streets. No one stays there long, and no one can explain why - something's not quite right there.

Now the Council is renovating the district, and a new company is overseeing the work. There will be street parties and events to show off the newly gentrified neighbourhood: clowns and face-painters for the kids, magicians for the adults - the street entertainers of Cardiff, out in force.

None of this is Torchwood's problem. Until Toshiko recognises the sponsor of the street parties: Bilis Manger.

Now there is something for Torchwood to investigate. But Captain Jack Harkness has never been able to get into the area; it makes him physically ill to go near it. Without Jack's help, Torchwood must face the darker side of urban Cardiff alone...

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.
