A synopsis for the upcoming Torchwood audio adventure, Lost Souls, has now been released by the BBC. The episode will take place after the events of Exit Wounds and will feature Captain Jack, Gwen, Ianto and Martha. It will broadcast on BBC Radio 4 next month and the synopsis can be viewed below;

"Somewhere out there in that chaos of darkness and light, of science and protons, of gods and stars and death... somewhere there's an answer."

The Torchwood Institute was founded by Queen Victoria in 1879 to protect the British Empire against the threat of alien invasion. By 2008, all that remains of the organisation is a small team based in Cardiff. And now, following the tragic deaths of two of their colleagues, the remaining three - Captain Jack Harkness, Gwen Cooper and Ianto Jones - have to protect the human race against another unknown force from the darkness.

Martha Jones, ex-time traveller and now working as a doctor for a UN task force, has been called to CERN - the world's largest particle physics laboratory in Geneva - where they're about to activate the Large Hadron Collider (LHC).

The LHC is a particle accelerator which has been built deep underground in a 27km tunnel under Switzerland and France. Once activated, the collider will fire beams of protons together, recreating conditions a billionth of a second after the Big Bang - and potentially allowing the human race a greater insight into what the Universe is made of.

But so much could go wrong - it could open a gateway to a parallel dimension, or create a black hole - and now voices from the past are calling out to people and scientists have started to disappear...

Where have the missing scientists gone? What is the secret of the glowing man? What is lurking in the underground tunnel? And do the dead ever really stay dead?

Lost Souls is written by Joseph Lidster who wrote A Day in the Death for the second series of Torchwood and will air on the 10th September at 2:15pm on BBC Radio 4. Lucy Montgomery and Stephen Critchlow will star in the episode alongside John Barrowman, Eve Myles, Gareth David-Lloyd and Freema Agyeman. What do you think of the synospis for Lost Souls?
