Savage Streets (1984)

Brenda (Linda Blair), charismatic leader of the “Satins,” a group of lively and charming high school girls, sees her life turned upside down by an act of brutal violence. When her deaf-mute sister (Linnea Quigley) is attacked by a gang, Brenda decides not to rely on traditional justice. Determined to take revenge, she leads the Satins on a dangerous hunt for those responsible.
During the opening credits, Linda Blair walks through the city wearing a very tight blue shirt and no bra. Her nipples are visible under the fabric. At the ninth minute, Suzee Slater is with a group of guys. One of them pulls down her shirt to expose her large breasts. At the twenty-sixth minute, Linda Blair and Rebecca Perle fight in the showers of a gym. Around them are several naked actresses. At the same time, Linnea Quigley has sex with some guys on the floor of a bathroom. At the fifty-first minute, Rebecca Perle fights with Linda Blair again, this time in a classroom. Rebecca falls to the ground and Linda rips her shirt off. The topless girl gets up and runs out of the classroom. At the sixty-second minute, we see Linda Blair naked in the bathtub, deep in thought, with a cigarette in her hand.
