This fifth season of the popular series changes everything†¦ and you've gotta be ready.

Out now, the official continuation of Torchwood (2006-present)! Returning to its Cardiff roots after the events of Series 4 - Miracle Day, the Torchwood team are back in Series 5 - Aliens Among Us!

Starring John Barrowman, Paul Clayton, Alexandria Riley, Jonny Green, Sam Béart, Kai Owen and Eve Myles, this brand new Torchwood has some new characters joining the surviving original team members, and the stakes have never been higher.

This twelve episode series kicks off with Part 1, with stories from fantastic writers James Goss, Juno Dawson and AK Benedict.

5.1 Changes Everything by James Goss

Tyler Steele has washed up in Cardiff looking for a fresh start. A disgraced journalist, he’s looking into the Red Doors movement – are they really behind the terrorist attacks on immigrants? Who is stirring up the racism and hatred in the city, and what does outsourcing contractor 3Sol have to do with it? Tyler finds out that Torchwood - a secret organisation that everyone thought long gone - is back in business. Tyler realises that this is the second chance he's been looking for, and he'll do anything to be a part of it.

5.2 Aliens & Sex & Chips & Gravy by James Goss

Has Cardiff really been invaded by aliens? Tyler thinks he’s found a lead – the daughter of the mysterious Ro-Jedda is getting married and has booked a private party. If Torchwood can infiltrate it, there’s a chance they’ll end up closer to the truth. Free bar, canapés, and the chance to find out what’s really going on. What could possibly go wrong? Soon Torchwood are on the run for their lives, and learning more than they ever wanted to about alien life.

5.3 Orr by Juno Dawson

Vincent Parry is the most successful property developer in Cardiff. A while ago he made an agreement with the mysterious Ro-Jedda, and it is an arrangement he has come to bitterly regret. Something has to be done – but it’s going to cost him everything he loves. With time running out for Cardiff, Torchwood encounter an alien who knows them only too well.

5.4 Superiority Complex by AK Benedict

Poverty and homelessness are on the rise in Cardiff. The streets are full of the desperate and the dispossessed. So, of course, it’s the right time to open a 7-star luxury, all-inclusive hotel. And, naturally, the hotel is for aliens only. As the humans stand outside the gates and look hungrily in, there’s one thing that makes them smile. Someone is murdering the guests.

“Aliens Among Us is unlike any other Torchwood release to date,” says director Scott Handcock, “It’s a new team, full-cast, driving the story forward beyond Miracle Day. Unlike releases like Outbreak, or Before the Fall - which are self-contained - the format of tackling ‘Series 5’ has allowed us to build a larger recurring cast of characters, and for James Goss and I to plot out a more-involved, ongoing story arc. Each of the individual stories are standalone, but there’s something far greater too, and elements introduced here will feed into Part 2 and beyond.

“It’s been a terrific challenge! And, of course, taking the series forward means we can afford to be unpredictable. There are things in Aliens Among Us that will really surprise the listeners - they surprised us when we suggested them - and even the trailer for Part 2 will leave listeners waiting impatiently for October. It’s a wild ride!”
