Rhys (Kai Owen) joins wife Gwen (Eve Myles) on a rescue mission
The creator of the Cardiff-based sci-fi drama series Torchwood says it's strange how world events seemed to have mirrored his latest storyline.
Russell T Davies says Torchwood: Children of Earth shows what happens when society starts to snap.
"Since we wrote this, the world economy has been perilously close to collapse, and along comes swine flu," he notes.
"At various points you discover in the Torchwood story that the whole thing was kicked off by a flu outbreak."
Interviewed by Jamie Owen and Louise Elliott of BBC Radio Wales, he added: "Our whole comfy lifestyle where we sit down and have a nice takeaway pizza and watch television with the lights on, or the fire on if it's cold outside ... all of that could just snap like that and we could be scrabbling in the gutter for food."
Torchwood: Children Of Earth follows the alien-chasing team as they battle for the future of the human race against the fiercest force they have encountered.
An ordinary day becomes one of terror as every child in the world loses their ability to function properly.
John Barrowman felt the cut in episodes was like a punishnment
As violence erupts and the world descends into anarchy, the Torchwood team is forced to go underground to save themselves and come up with a plan to save mankind.
John Barrowman, who plays Captain Jack, praised the writing but said that cutting the new series to a single five-part story felt like "we were being punished".
"Other shows move from BBC Three and Two to One and they don't get cut," he told Radio Times magazine.
"So why are we? It felt like every time we moved we had to prove ourselves."
Torchwood: Children of Earth can be seen on BBC One at 9pm nightly from Monday-Friday 6-10 July and on the BBC iPlayer for seven days after broadcast
