Jennifer cuts the rope and drops the dead body in the river. Matthews struggles, but is slowly strangled to death as Jennifer watches with a wicked-looking facial expression. As he becomes oblivious to his surroundings, she strings a noose around his neck and hangs him. At the cabin, Matthew arrives where Jennifer entices him to have sex with her under a tree. Hearing that it's from Jennifer's address, he takes the groceries, and a knife he steals from the grocery store butcher unsure of what Jennifer plans to do with him. One day, Jennifer calls in a grocery order knowing Matthew will deliver it. Jennifer then begins spying on her assailants first by following Matthew home from the local grocery store to his parents house, and the next day she follows Johnny home from the garage to his house where he has a wife and two young children. One day, the men learn Jennifer has survived and they beat Matthew up for lying to them about killing her. She goes to a church and asks for forgiveness, vowing to kill all four of the men who violated her. She silently sits around her house, chain-smoking, and avoids looking into mirrors to avoid seeing her maimed face now sporting some permanent scars and ugly bruises from her beating. Over the next two weeks, a traumatized Jennifer pieces both herself and her manuscript back together. The four then take off in their speedboat. Matthew cannot bring himself to do it, so he dabs the knife in her blood and returns to the other men claiming he has killed her. Johnny realizes she is a witness to their crimes and orders Matthew to go back and stab her to death. She passes out on the floor covered in mud from the woods as well as her own blood. When Jennifer scratches at Stanley's face, she is savagely beaten. The other men ridicule her book and rip up the manuscript, and Stanley sexually assaults Jennifer and rapes her too. Matthew finally rapes her after drinking alcohol, but says that he can not reach orgasm with the other men watching. A little later, after Jennifer crawls back to her house they attack her again. The four guys flee from the scene of the crime in their speedboat. They allow her to escape but track her down shortly afterward and Andy brutally rapes her anally. Matthew refuses to have sex with her so Johnny rips off Jennifer's bikini and rapes her. Jennifer puts up a fight by punching Johnny, but is chased by the men through the forest.
She realizes they planned her abduction so Matthew can lose his virginity. As she tries to escape, she's met by Johnny, while Matthew hides in bushes nearby.
