If you are a fan of endless lesbian orgies this film may be exactly the right stuff for you: see naked chicks having sex in their prison cells, under the shower, with the female attendants... here and there even some short hardcore sequences are brought on. There are some quite tame torture scenes and a subplot about the trade with female slaves, which is not further developed..!
"Bare behind bars" is probably the best WIP (stands for "Women-In-Prison")-flick ever made, because it doesn´t take itself too serious and it´s often full of unconscious humor! The best scenes has this weird Marilyn Monroe-like nurse, who uses an ananas as her dildo and exploits the female prisoners as their sex-bunnies.
If you want to know why this film is banned in countries like the U.K. or Germany check out the last third, which is the grossest part of this movie! Three outlaws are able to escape and on their run they murder a family, just for drinks and food. The climax of this crime is when one of the girls castrates the dead husband and feeds the cut off dick to his pesky barking dog..! Another castration-scene is featured some minutes later... However, there´s no happy ending for the girls: two of them return to prison, the third one becomes a prostitute and gets shot by her pimp..!
"Bare behind bars" belongs to those movies you may need a shower after watching it. Nevertheless it can be pretty entertaining if you have a sense for such films. If you like WIP-flicks try to find Jess Franco´s "Sadomania", too!!
