When a burglary turns into a slaughter, Torchwood suspect alien involvement. Who is Beth, and can she be as innocent as she seems? However, when the investigation escalates into a city-wide assault, Captain Jack realises that the whole planet is in danger.—Anonymous
After a burglary in her flat, the only person left unharmed is Beth. The two burglars and her husband were all severely beaten but she doesn't even have a scratch on her which leads Captain Jack to think that she's the one who inflicted the beatings. They bring her into the Hub for a series of tests and learn that her body has been invaded by a dangerous alien species. She's not aware of the creature's presence but it is gathering information in anticipation of an invasion of the Earth. When they find a way to turn off Beth's internal transmitting device, they awaken other members of cell who immediately go to a nuclear arms depot intent on causing mass destruction.—garykmcd
