Prisoner

Rita is gutted and becomes disillusioned when Merle knocks her out in a dispute stirred up by Kath and Janet. Rodney holds an aerobics class for the prisoners, which ends in him being made a fool of. Janet plays silly buggers and messes around with the video tapes in an attempt to get Rita's girls into trouble. Joan and Andrew have a talk and try to reach a new understanding. Tension flares up between the three trainees.
