Desolation Angels (1982)

Fun in the sun turns into a nightmare when a group of madmen take over a resort town in Desolation Angels (1982). Jilly (Kim Trengove), Joanna (Kerry Mack), and Liz (Marie O'Loughlin), three beautiful friends who attend an upper class private school together, decide that a weekend off in a remote town will be the perfect chance to relax. Unfortunately, they are dead wrong. The town has been taken over by a group of deranged psychopaths intent on killing the nubile maidens. Angelic blonde Kerry Mack takes of her shirt 30-mintues in to reveal her terrorized teen torpedoes. Ms. Mack will make you want to wack!
