Captain Jack Harkness, Gwen Cooper and Ianto Jones return for a brand-new adventure in Torchwood – Children Of Earth, a new five-part series for BBC One.

An ordinary day becomes a world of terror, as every single child in the world stops. A message is sent to all the governments of Earth: “We are coming”.

But as a trap closes around Captain Jack, sins of the past are returning, as long-forgotten events from 1965 threaten to reveal an awful truth.

Torchwood are forced underground, as the government takes swift and brutal action. With members of the team being hunted down, Britain risks becoming a rogue state, with the mysterious and powerful 456 drawing ever closer.

Captain Jack (John Barrowman), Gwen (Eve Myles) and Ianto (Gareth David-Lloyd) are helpless, as events escalate until humankind faces the end of civilisation itself.

Due to the popularity of the series, Torchwood has made a swift move from BBC Three to BBC Two, with the new instalment, Torchwood – Children Of Earth, finding itself on BBC One.

In one epic story, told over five episodes, the new series promises to be Torchwood’s greatest adrenalin-fuelled, high-octane adventure to date. As they battle against the odds, do they stand a chance of saving humankind?
