Sun Hill has been given a new "crime car" for quick arrests and Boyden, Hagen and Proctor are chosen to crew it, much to the other officers' annoyance. Proctor is given a list of targets by DI Deakin and has been told to collar at least one to count towards his appraisal. However, Boyden is more concerned about his own collars. TSG have been assigned as cover as the relief are very low on manpower, but seem more determined to ruin the collars of the crime car than actually do any work themselves. When they dangerously vy for an arrest, disaster strikes. Meanwhile, Mannion arrives for a tour of the station just as the CAD room goes down due to an electrical fault, a fault caused by someone whom Ackland later discovers to be a regular in the cells.
