After witnessing a gangland shooting, flatmates Leanne and Rhona are placed in a witness protection scheme. Wannabe actress Leanne sees this as an opportunity to "improv" new characters, Rhona is rightly terrified.
The girls need to retrieve Leanne's bag from Patrick's house, but in doing so uncover a closely-guarded secret about him. A secret in the police force means the girls are not as protected as they thought.
After arousing the suspicions of scary neighbour Jackie, the girls are forced into a series of increasingly uncomfortable lies. Meanwhile, DJ Sound as F*** makes a discovery that could lead him to them.
When Patrick contacts Leanne, Rhona insists she severs all ties with him. Nosey neighbour Jackie overhears something that could expose their secret. The police re-examine the murder of Mrs Hobbs.
The net is closing on Leanne and Rhona. Will Forrest lead the gang to the girls? Will Appraisal crack under pressure from the police? Will the discovery of the murder weapon be a ticket home for the girls?
