Creeper (2012)

Fed up with all the weirdos, the predators and the creepers lurking undetected in the online obscurity, four friends concoct a recipe for revenge against all men and decide to even things out by exposing a hardened pervert, and ultimately, destroy him. Soon, after scouring the net's dating websites, they will dig up the perfect candidate, a real creeper in the person of Jerry Tobin, a menacing mute veteran from the Iraq war who is on heavy medication, and without delay, the girls will tease him by giving Jerry sick tasks, that if he wants to advance, he must do as ordered to get his reward. As Cally, Heather, Erica and Dana get really brutal for days with the intention to harm the unaware Jerry, they will finally succeed, leaving him all alone and humiliated. But presently, one year later, Jerry, who is off the psychiatric therapy that helps keep his well-hidden beast at bay, still roams the streets longing to punish the depraved girls who debased him, determined to make them suffer. Will the girls live to breathe another day?
