A man has been murdered in an ongoing spree, and PC Gwen Cooper is surprised when four shady figures take over from the police. They identify themselves only as "Torchwood". One woman, called Suzie by a tall American in a long coat, takes out a metal gauntlet and brings the victim back to life for just two minutes. The American identifies himself as Captain Jack Harkness, but Gwen researches and finds that the last person of this name vanished in 1941. She uses the guise of a pizza delivery person to find Torchwood Institute, only to discover they were expecting her. She is introduced to the entire team, and also shown a Weevil. However, her memory is erased. She meets Suzie again, who admits to the death and shoots herself. Gwen then remembers everything, and is given a job at the institute.
