Heather (Linnea Quigley), the deaf-mute sister of Brenda (Linda Blair) is gang-raped in a drawn-out, violent scene at the beginning of this routine vengeance movie, a scene that provides the motivation for Brenda's rampage through the rest of the film. Dressed in a special outfit that bares enough skin to suit the standards of this genre and armed with a crossbow, Brenda goes after the young punks in the "Scars" gang who raped her sister -- with predictably gory results. Surrounding this miniature Charles Bronson is a society burdened with parodies of "good" people: the school principal who is only superficially tough, and the upper-class teens whose thought processes were arrested shortly after kindergarten. Stereotypical and transparent, this teen movie is interesting because it does promote a woman in a "hero" role, but the subject matter and violence will not appeal to everyone.
