Separate from the government, outside the police, beyond the United Nations: Torchwood sets its own rules. Led by the enigmatic, ever watchful Captain Jack Harkness, the Torchwood team delves into the unknown and fights the impossible.

From an underground base built on a rift in time and space, the team responds to any alien threat - a meteorite crash landing, sightings of extra-terrestrial technology, an unusual autopsy report, the spread of a deadly alien virus...

Everyone who works for Torchwood is young, under 35. Some say that's because its a new science. Others say its because they die young.
