Biography
The couple, living on 114 Brodsky Street, were woken up in the night by a loud noise from inside her flat. After sending her husband Mike to investigate, Beth called the police. When the police came, one of the burglars had been killed and the other severely injured. Mike was unconscious and Beth couldn't remember anything. The police called in Torchwood to deal with the case. Beth was taken to Torchwood base to be interviewed. She swore she didn't know anything. However, strange things happened: the lights blew whenever she got upset and Owen could not get a syringe or even a scalpel inside her. Her presence also frightened Janet the Weevil.

Jack Harkness used a mind probe. This made Beth recite a name, rank and serial number. Her arm opened to reveal Cell 114 technology. Toshiko Sato suggested they freeze her and wake her when they knew how to make her human. Jack agreed. When they checked on Beth later, she had vanished. Owen realised she knew about Torchwood and could fool the equipment. Beth had gone to Mike's bedside to say goodbye to him. However, when she hugged him, she accidentally killed him when her arm turned into a blade. The Torchwood team arrived and captured Beth.

Simultaneously, the other sleeper agents had been activated. Jack asked Beth to track them. She reluctantly used her arm to discover that there was only one left. They tracked the remaining sleeper agent, a man named David. Back at the Hub, Gwen was set to refreeze Beth, but she pretended to try to kill Gwen to trick the Torchwood team into shooting and killing her. (TW: Sleeper)
