Amazingly stupid. This looks like one of Jess Franco's pieces of crap exploitation movies from the 70s. The girls were naked, but had no sunburn, The guards carried M-3 sub machine guns, but had bandoliers full of rifle ammunition. They also wore jungle camos out in the desert. The guy didn't even try. He cranked these stinkers out as quickly as possible and as cheaply as possible.
in my prison they would not have footwear of any kind and they would have ankle and wrist shackles with chains to keep them at various lengths for activity control
