Crazy Animal (2007)

Apparently, to a rapist frat boy (Jeff) and his friends (Jen, Meese, etc.), there is a crazy 80s glam rock metal head who lives in a shack in the woods named Ricky. When the frat boys and girls wander away from their beach house and find him, Ricky ties them up and sings them cheesy 80s heavy metal songs until one confesses to a heinous crime - We soon realize that Ricky is one of the good guys, who has teamed up with Jen, the head frat girl that set up this whole beach house vacation so that she could capture Jeff's confession to her high school rape on video. Just as the bad frat boy confesses, he breaks free from his ropes and begins going on a killing spree. Will more innocent be hurt by Jeff? Or will Ricky, Jen and her friends bring justice to this horrible male chauvinist rapist?
