An attempted robbery in urban Cardiff ends with one of the criminals dead with a vicious wound left by some kind of blade, and the other in a coma – and a traumatized couple who seem to know nothing about what happened. Torchwood takes over the investigation from the police, and their interest quickly homes in on Beth, one of the couple who was attacked. Her statements don’t seem to add up, but her reactions to being in Torchwood custody seem perfectly normal for a scared civilian. When Jack insists on scanning her with a mind probe, only then does Beth’s true nature emerge – she’s not human at all, but an alien sleeper agent in human form, gathering intelligence and preparing to clear the way for an invasion. When the probe is discontinued, Beth’s seemingly human personality reasserts itself, but her alien physiology makes it impossible to isolate her by something as mundane as stasis or cryogenic freezing. She escapes the Torchwood hub with Jack and Gwen on her trail, but massive explosions, brutal murders and other incidents in and around Cardiff reveal that Beth isn’t the only sleeper agent there. The entire cell has reverted to a single-minded drive to complete the mission – and begin the invasion ahead of schedule.
