The term 'grindhouse' gets bandied about a little too much these days (thanks, QT), but Schoolgirls in Chains is the real deal, a sleazy, low-budget shocker aimed specifically at drawing in a crowd keen to see pure exploitation—in this case, beautiful women abducted and abused by a pair of demented brothers, who have been raised by their sick mother to believe that ALL pretty young females are evil (when, in fact, it's only about 90% of them).
Trapped in the grungy basement of a remote house, the captured women are kept as playthings for man-child John (John Stoglin), whose over-enthusiastic approach to his depraved games often results in his 'toys' being broken (and consequently buried in the family's vegetable patch). Meanwhile, big brother Frank (Gary Kent) is on hand to keep the ladies in control, under the ever watchful gaze of domineering, woman-hating Mother (Greta Gayland).
When John's game of hide and seek with his latest toy Sue (Merrie Lynn Ross) ends up with the gal receiving both barrels from Frank's shotgun, Mother agrees to the abduction of Bonnie, an attractive student who John has been spying on. After Bonnie goes missing, however, her lover—a professor at her college—sets out to find what has become of her...
With a dab of psychological drama (ala Psycho), a soupçon of incest (mother loves her lads a little too much), a smidgen of rape (Frank forces himself on pretty prisoner Ginger, played by lovely Suzanne Lund), a touch of torture (I want to play doctor!), and a whole lot of grubby, low-rent photography accompanied by a suitably discordant soundtrack (complete with an effectively unsettling nursery rhyme theme), Schoolgirls in Chains achieves exactly what it sets out to do—entertain its audience through a series of sensational and sordid scenes in which girls in peril are subjected to all manner of horrors.
It's not exactly art, but it sure is fun (but don't tell mama I said so: she doesn't approve of me watching filthy girls). 7.5 out of 10, rounded up to 8 for IMDb.
