Torchwood One: Before the Fall

London, 2005. Yvonne Hartman is the undisputed head of Torchwood One.

Above the government, beyond the police, she has excellent people skills; enjoys regular tea with the Queen; and effortlessly defends the British Empire from alien threats.

Yvonne Hartman is excellent at her job, and inspires devotion in everyone who works with her - until, one day, she makes a terrible mistake.

We all make mistakes. But only at Torchwood can a single mistake plunge your world into interstellar war.

Yvonne Hartman's facing the fight of her life. One she's going to win. Torchwood has now been in existence for 10 years from its debut in 2006 as a Doctor Who spin-off created by top TV producer and writer Russell T Davies.

Torchwood has appeared on both UK and US television, BBC radio productions, novels, and now - courtesy of Big Finish - in new audio plays.

Torchwood One was first referenced in the hugely-rated modern Doctor Who stories Army of Ghosts and Doomsday.

This is the first look at the London-based team before those events.

Writer Joseph Lidster not only adds another Big Finish Torchwood script to his CV, but wrote for the original TV series too.CAST: Tracy-Ann Oberman (Yvonne Hartman), Gareth David-Lloyd (Ianto Jones), Gerard McCarthy (Dean), Sophie Winkleman (Rachel Allan), Robert Daws (Soren), Tim Bentinck (Thomas), Nisha Nayar (Guleraana), Lorelei King (Pippa), Damian Lynch (Kieran), Simon Hickson (Ziggy), Rachid Sabitri (Mehdi), Helen Goldwyn (Receptionist), Philip Childs (Dave).
