A storm is brewing: the water levels of the Bristol Channel are inexplicably rising, and Cardiff Bay is under threat from the worst flooding in years. In the midst of the climate chaos, Torchwood is called to investigate a series of gruesome murders.

Martha Jones, ex-time traveler, has been called to CERN, the world's largest particle physics laboratory, in Geneva. They're about to activate the Large Hadron Collider, designed to recreate conditions after the Big Bang and thus give an insight into what the Universe is made of. But so much could go wrong: it could open a gateway to a parallel dimension, or even create a black hole.

John Barrowman, Eve Myles and Gareth David-Lloyd star in seven full-cast BBC Radio 4 dramas based on the hit BBC TV series. In "Lost Souls" by Joseph Lidster, voices from the past are calling out from the Large Hadron Collider at CERN, and scientists are disappearing. Can Torchwood help? 'Asylum' by Anita Sullivan sees PC Andy Davidson turn to Torchwood after he arrests a very unusual shoplifter. 'Golden Age' by James Goss finds the team in Delhi, on the trail of a dangerous energy field.

A friend of Gwen's has recently done an impressive bit of slimming, thanks to a new Cardiff weight-loss clinic with an incredibly simple system, and now Rhys wants to give it a try. Elsewhere in the city, an ordinary woman with superhuman strength and a extraordinary hunger is attacking people and eating her victims.

It starts with a series of unexplained events. Earth tremors across the globe. Women being driven insane by their heightened and scrambled senses. And the world is starting to notice - the number one Twitter trend is #realfemmefatales. Governments and scientists are bewildered and silent. The world needs Torchwood, but there's not much of Torchwood left.

Something is here that shouldn't be here. Something is watching. In Cardiff's secret heart, the members of the Torchwood team struggle to define and locate the intruder, and contain it before anyone gets hurt.

When Oscar Lupe appears 20,000 feet up in the air, his body is frozen solid and free-falling to earth. It shatters on impact. Soon after, a CIA Special Activities Division squad goes rogue with a cargo marked ‘Torchwood’ that they’ve been escorting from somewhere called Cardiff. The Agency puts Rex Matheson on the case. As the strange deaths pile up, Rex realises there must be experimental tech out there, but someone is obstructing him at every turn. Rex is the CIA’s golden boy - but has he met his match in the evasive Mr Wynter…?

John Barrowman, Eve Myles and Gareth David-Lloyd star in three Torchwood radio adventures from the Lost Files, each set before the TV story Children of Earth. The Devil and Miss Carew sees Gwen and Rhys involved in a nursing home mystery. Submission finds the Torchwood team heading for the bottom of the sea – the Mariana Trench – after they intercept a distress call. The House of the Dead sees a special séance being held at the most haunted pub in Wales.

Gwen and Rhys are on the run. Rhys was hoping this meant a windswept cottage on a cliff top, but he’s had to settle for a miserable caravan in the isolated village of Rawbone. With the locals taking an unhealthy interest in their daughter, Gwen and Rhys start to realise that something is very wrong. As they uncover the village’s terrible past, Gwen discovers that Torchwood will never leave her behind, and now she and Rhys stand alone in defence of the Earth. And the children of Rawbone can only bring her closer to the secret forces that want her out of the way.

On the trail of a dangerous energy field, Torchwood are led to Delhi. There they witness the simultaneous disappearance of hundreds of people, and Jack discovers that the field centres on an old colonial mansion - Torchwood India. Jack is shocked to find that Torchwood India is still going strong - he shut it down himself over 80 years ago. He's even more surprised to find that its members, including his old flame the Duchess, haven't aged a day.
