In the station locker room, PC Roz Clarke tells PC Cass Rickman that she's got tickets for a hot club. As they laugh, Vicky Hagen enters and the room goes silent. Hagen demands to know what they are saying about her and Sergeant Boyden. She haughtily boasts that she might try Superintendent Chandler next time. Hagen joins PC Tony Stamp in the area car but is unimpressed by his lack of speed. They attend the mugging of a pensioner Archie Dodds who has had his wallet taken by a young kid. When the mugger is spotted assaulting another pensioner, Stamp and Hagen set off in pursuit. However he escapes when Stamp stops to help the victim. Hagen sarcastically dubs him 'Florence Nightingale'. That evening Hagen turns up, uninvited, at the girls' night out and quickly picks up Rob Seaton, but her amorous advances have catastrophic consequences.

PC Des Taviner finds a terrified shoeless Chinese man on the Coal Lane estate, but when he is taken to the station for interview, there are serious doubts about the Chinese interpreter sent by the Yard, Mai Ann Wey. Unaware of these doubts, Taviner seeks Mai Ann's help when he discovers a flat full of illegal immigrants on the estate. When the immigrants all disappear and there are signs of violence, it becomes clear that Mai Ann is working for the snakehead gang, and Taviner turns to a reluctant Chinese priest, Father Kwong, to locate the immigrants. The court case against the boys who gang-raped Louanna Shaw nearly falls apart when Louanna's friend Beth loses her temper in court and the defence lawyer sees PC Kerry Young discussing the case with her husband PC Luke Ashton. Only Insp. Gina Gold's forceful testimony saves the day, but Young is furious with Ashton for jeopardising the case and insists their marriage is over.
