Four young girls at an institution for criminally and socially undesirable females are brought before a visiting governor for their part in a riot. The charges are read out and there is only one course of action for the governor. The unruly behavior of this kind will not be tolerated under his regime. Tough new measures are to be brought in immediately. Corporal punishment will be re-introduced. Spanking, strapping and caning are to be applied to the bare bottoms of those girls who do not conform. Each girl must strip out of her uniform of blue blouse and navy dungarees. The governor performs his task with great aplomb.
