Torchwood (2006 TV Series) - Season 1 - Episode 5

Season 1 (13 episodes, BBC Three, 2006–2007) introduces police constable Gwen Cooper, whose curiosity about a brutal murder leads her to Torchwood. She meets immortal leader Jack Harkness and the core team Owen Harper, Toshiko Sato, Ianto Jones, and Suzie Costello and is drawn into their world of alien artifacts, dangerous cover‑ups, and morally gray operations. Standalone cases (a meteor crash, a time‑viewing “ghost machine,” a Cyberwoman, fairies, and more) build toward Suzie’s betrayal and death, cementing Gwen’s place on the team and setting up ongoing tensions about loyalty and ethics.
