After witnessing a gangland killing, flatmates Leanne and Rhona are placed in witness protection. Leanne leaps at the chance to create an extravagant alter-ego whilst Rhona is determined to get back to her old life. After Leanne’s ‘acting’ threatens to blow their cover Rhona decides to take matters into her own hands.

The girls need to get Leanne’s bag back from criminally connected Patrick’s house. But discovering a closely guarded secret of Patrick’s leads Leanne to become more deeply involved. Meanwhile, there’s a seedy secret in the police force and the girls might not be as well protected as they think.

Patrick contacts Leanne out of the blue but Rhona is insistent that she cuts all ties with her former lover. Meanwhile, their nosey neighbour, Jackie, overhears something that could lift the lid on their double life. In Bristol, the police re-examine Mrs Hobbs’ murder case and Sergeant Forrest comes under pressure to reveal the whereabouts of the girls.

The net is closing in on Leanne and Rhona… Will Forrest lead the gang to the girls? Will Appraisal crack under pressure from the Police? Could the discovery of the murder weapon be the girls’ ticket home? Series finale.
