I remember thinking this movie was one of the most amazing things I'd ever seen when I viewed it back in the VHS days as a young fellow. Watching it more recently I'm not exactly sure why it stood out so much to me from all the other women-in-prison flicks from this era. Maybe I just hadn't seen enough of these movies yet at that point. It's still a pretty good watch though you get all the expected thrills and blood-spills, shower scenes, cat-fights, machete-mayhem, machine-gun madness and horribly oppressed women fighting back against horrible sleazy men.
This has a whole slew of AKA's including CHAINGANG GIRLS, HELLFIRE ON ICE, my personal favorite: SHE-DEVILS IN CHAINS and CAPTIVE WOMEN 3( a full rundown of the CAPTIVE WOMEN series is available here)
