Savage Streets (1984)

After a night out on the streets of L.A., lively high school student Brenda and her all-girl team The Satins decide to play an innocent prank on the brutal street gang of dope-dealers, The Scars. But before long, Brenda's beloved deaf-mute sister Heather catches the eye of their vicious leader, Jake--and he and his companions sexually assault the defenseless girl, leaving her for dead as payback. Now, there's no turning back, and as blood demands more blood, vengeful Brenda sets out on a violent journey of retribution to settle the score. Her friends are some lethal bear traps and a mighty crossbow. Who can stand in the way of the leather-clad female avenger?
