The sheriff brings two more residents, nymphomaniac lovers Eddie and Tina, after catching them having sex on neighbor Ethel Hubbard's lawn. Ethel Hubbard and her son Junior show up and threaten to have the house closed down if the teens do not stop sneaking onto their property.Vic kills Joey with an axe and is subsequently arrested. Attending ambulance drivers Duke and Roy Burns discover the body. Roy is saddened by the death, but Duke believes that the murder was a harmless prank. That night, punks Vinnie and Pete are murdered by an unseen assailant after their car breaks down. The following night, Billy and his friend Lana are killed with an axe. Panic begins to ensue, but the mayor refuses the sheriff's claim that somehow Jason Voorhees has returned.The next day, more murders occur when Tina and Eddie sneak off into the woods.

Meanwhile, Tommy and Pam accompany Reggie to visit Reggie's older brother Demon and his girlfriend Anita. While there, Junior has a fight with Tommy, and he runs off when Pam tries to stop it.

Pam rushes toward the barn, chased by Jason, but he is struck by a tractor driven by Reggie. They run into the barn and hide as Jason comes to find them. Tommy comes shortly after and believes Jason to be a hallucination until he is attacked. Together, they get Jason to fall out of the loft window, and he is killed on a harrow below. The killer is revealed to have not been Jason, but was Roy Burns all along.At the hospital, the sheriff tells Pam that Joey was Roy's son and after seeing him slaughtered, he adopted Jason's identity to kill everyone at the house. She goes to Tommy's room, who awakens and stabs her before Tommy awakens to a hallucination of Jason. Facing his fears, he makes Jason's hallucinations disappear.
