"SAVAGE STREETS" offers R-rated exploitation with a vengeance. The movie, which stars Linda Blair, as the leader of a high school gang of girls called the Satins, suggests a hybrid of ''Porky's'' and ''The Road Warrior,'' but set on Sunset Boulevard.
The film hangs its yards of nudity, violence and obscenity on the story of what happens when the Satins run afoul of the Scars, a cackling band of cocaine dealers and sex maniacs. In reprisal for a practical joke, the Scars rape Brenda's deaf-mute sister, Heather, in the gym while Brenda is distracted in a screaming fight in a nearby locker room. Later, after a fracas in a local rock club, they pitch Francine, a pregnant bride-to-be and charter member of the Satins, over a bridge.
It remains for Brenda to seek retribution. Donning a studded black body suit and armed with crossbow, switchblade and flammable fluids, she makes sure that the Scars get their due in a protracted and grisly finale.
"Savage Streets" doesn't even have a rudimentary continuity between its scenes, and its performances are crude cartoons. The one quality it does exude is a kind of manic delight in its own awfulness.
