List of Torchwood episodes

"Lost Souls" is an original BBC Radio 4 audio play written by Joseph Lidster and is a spin-off from the British science fiction television series Torchwood, itself a spin-off from Doctor Who. It aired on 10 September 2008 in the Afternoon Play slot as part of Radio 4's Big Bang Day which celebrated the switching on of CERN's Large Hadron Collider that same day.Andrew Marr introduced the audio play live from CERN. An mp3 version of the audio play was freely available until 18 September, when the play was released on CD and as a purchasable download.

Torchwood Three are chasing a Weevil through Cardiff Bay. Dr. Martha Jones phones Captain Jack Harkness, requesting help. Jack immediately agrees to meet Martha when she says people are disappearing from the CERN facility in Switzerland, where she's working. Martha suggests they go undercover, and Torchwood set off for Geneva.

Gwen Cooper says there aren't any records of the disappearances, but instead on the Large Hadron Collider, or LHC. Jack explains to her and Ianto Jones that CERN seeks the 'Higgs Particle', the fundamental particle of existence. CERN had found a way of examining the building blocks of matter itself; and built the world's largest particle collider which runs from Switzerland to France, in a 27 km round tunnel. Jack excitedly states that the plan is to collide protons moving at the speed of light together, to produce what would effectively be like the "Big Bang". Jack guesses the people may have discovered something unusual and were forcibly removed. He explains that the particle collision is thought to expose parallel dimensions, create black holes or turn the world inside out. After noticing Gwen and Ianto's expressions, Jack assures them that it would all be fine since it's theoretical.
