Watch an exclusive sneak preview of what's to come in the new series.
Torchwood will be back on BBC One at 9pm later this year.
In one epic story told over five nights the new series, to be broadcast for the first time on BBC One later this year, promises to be Torchwood's greatest adrenalin-fuelled, high octane adventure yet.
Torchwood: Children of Earth re-joins Captain Jack (John Barrowman), Gwen Cooper (Eve Myles) and Ianto Jones (Gareth David-Lloyd) who are still coming to terms with the death of two of their closest friends. Despite their pain, they have a job to do.
This time they are faced with their fiercest threat to date - one which throws the future of Torchwood and the entire human race spiralling into danger. They battle against the odds but do they stand a chance of saving mankind?
