==Plot==
The day after the events of Friday the 13th Part 3, police and paramedics are cleaning up the mess left at the lakefront property of Higgins Haven by hideously deformed mass murderer, Jason Voorhees, who brutally murdered all, but one of the teenagers visiting the property.  After being hit in the head with an axe by sole survivor, Chris Higgins, Jason is taken to the Wessex County Morgue.  Later that night, Jason arises, having survived his injury, would murder to workers at the Wessex County Morgue.  He would first kill the coroner, Axel by slitting his throat with a surgical hacksaw, followed by killing Nurse Robbie Morgan by gutting her with a scalpel.  He then escapes the morgue and heads back to Camp Crystal Lake .
Meanwhile, a group of teenagers would rent a house on the shores of Camp Crystal Lake and are headed to their weekend getaway.  These teenagers, include Paul, Paul's girlfriend, Samantha, Doug, Doug's girlfriend, Sara, Ted, and Jimmy.  Next door to the teenager's rental home, is another house that is owned by the Jarvis family, which include Trish Jarvis, her younger brother, Tommy Jarvis, and their mother, Mrs. Jarvis, along with their dog, a golden retriever named Gordon.  On the way to the rental house, the teenagers drive past a Pamela Voorhees's tombstone in a cemetery, and a female hitchhiker, who they ignore.  The hitchhiker, rejected, sits back down on the log and begins to peacefully snack on a banana.  Jason would come up from behind the hitchhiker and would stab her in the back of the neck with a knife, thus killing her.
The teenagers arrive and meet Trish and Tommy Jarvis, and then later meet two beautiful twins, Tina and Terri, that live in the area.  The group all goes down to the lake to go skinny dipping.  Tommy and Trish, on their way back from town, stop and while Tommy is fascinated, Trish struggles to shield Tommy's vision of the naked men and women skinny dipping in the lake.  The teenagers, carefree and having a good time, invite Trish to a party at their rented vacation house later that night.  Tommy and Trish continue to drive on and a little ways down the road, their car breaks down.  They are soon assisted by a hitchhiker named Rob Dier, who explains that he is out hunting for bears, but Tommy is quick to correct Rob and says there are no bears in the area, and Rob quickly refutes, but Tommy still finds Rob's reasons of being in the area a little suspicious.  After helping with their car, Trish invites Rob back to the Jarvis house to meet their mom, and Tommy shows Rob his room.
Night falls, and the teenagers, including Tina and Terri, are throwing a party.  Meanwhile, Jason begins his bloody rampage to continue his killing spree against teenagers invading his territory, while Rob is pitching a tent in the woods, as Tommy and Trish leave into town again.  Samantha grows jealous when Paul dances with one of the twins and leaves for the lake.  She starts skinny dipping and swims out to a raft in the middle of the lake.  But her relaxing ends quickly when Jason leaps from out of the water and stabs her from underneath the raft with a knife and up through her chest and through her back, thus killing her.  Paul goes to check on Samantha to see if she's alright, and swims out to the raft in the middle of the lake, as he sees her lying there.  He finally reaches Samantha and sees her dead in the raft, and swims back to shore in a panic.  Jason would then lunge out after Paul when he goes to climb the pier and Jason kills Paul after grabbing him in the crotch with a spear gun and squeezing it until his private sections pops.
Jimmy gets Tina to have sex with him, and Ted, Doug, and Sara begin watching some old, vintage stag films.  Terri tries to leave early on her bicycle, but Jason stops her when he kills her by stabbing her in the back with a spear and shoving her into the side of the house.  Mrs. Jarvis goes outside in the rain, only to be startled and was killed off screen.  Trish and Tommy return home from town and notice their mother missing and realize she is never gone for so long in a rain storm in the dark, while Jason gains entry into the rental home.  Jimmy finishes having sex with Tina, and goes into the kitchen to look for a corkscrew.  But it seems Jason has found the corkscrew first and jams the corkscrew into Jimmy's hand, followed by hitting him in the face with a meat cleaver, thus killing him.  Tina begins to get dressed and notices her sister's bicycle still outside.  She looks out the window, only for Jason to plunge through the window, since he was standing on a ledge beside the window, and grab Tina, throwing her out of the window and she lands on top of the teenager's parked car, thus dying in the process.
Trish goes looking for her mom and notices a tent set up in the woods and finds Rob there, whom tells Trish the real reason why he is at Camp Crystal Lake.  He tells Trish that Jason killed his sister, Sandra Dier, whom was killed, along with her boyfriend, Jeff, in Friday the 13th Part 2, and warns Trish that Jason may still be alive and in the area.  Trish and Rob run back to the house to check on Tommy.  Back at the rental home, Jason makes his way through the house and Ted becomes his next victim when the projector screen of Ted's vintage pornographic stag films shuts off, he gets close to the projector to check why it stopped working, and Jason stabs him through the screen with a knife in the back of his head, thus killing him.  Doug and Sara are upstairs having sex in the shower while all this is going on.  After they finish having sex, Sara leaves to go to her room and get dressed.  Jason sneaks into the bathroom and kills Doug by smashing his head into the bathroom wall and crushing his face and skull against the tile.  Sara returns to find Doug dead in the shower with blood everywhere.  She runs downstairs to the front door, which is locked.  An axe is thrown through the door and hits her in the chest, thus killing her.
Trish and Rob return to the Jarvis house and see that Tommy is okay.  They rush over to the rental house to check on the teenagers, along with Gordon, as Tommy stays back at his house.  Trish and Rob enter the rental house to find it empty.  Rob and Trish go down to the basement.  Gordon, frightened by something or someone, flees upstairs and escapes through a window.  Trish runs upstairs to find Gordon, but instead finds Doug's corpse.  She runs to the basement to warn Rob, but it's too late.  Jason attacks Rob and kills him with slitting his throat with a garden harrow, while he yells for Trish to run, and she does.  Trish, armed with Rob's machete, flees the rental house, running into the dead bodies of both Terri and Jimmy, and back to the Jarvis house.  Tommy and Trish then nail the front door shut.  After a few moments of silence, Jason hurls Rob's dead body through a window and smashes through another window, grabbing Tommy.  Trish fends off Jason, who breaks his way into the house.
Trish and Tommy run upstairs and lock themselves in Tommy's bedroom.  Jason begins to hack the door with an axe, with Trish snatching up Tommy's computer monitor and smashes it into Jason's head.  But Jason quickly recovers, and chases Trish out of the house and all the way back to the rental house.  Meanwhile, Tommy find some newspaper clippings from Rob's backpack about Jason as a child and Tommy sees a picture of a young Jason Voorhees bald, and Tommy decides to shave his head bald.  Trish runs from Jason throughout the rental house and manages to escape by jumping through the second story window.  She quickly returns back to the Jarvis house, and struggles with Jason, with two quick machete strikes, she splits in half his left hand and pierces through his chest, but it's all in vain.
Tommy runs downstairs, with his head shaved bald.  He distracts Jason by calling out his name, who falls into a deep trance, transfixed with Tommy resembling Jason as a child.  During this brief distraction, Trish grabs the machete and swings it at Jason's face, knocking off his mask and revealing his horrid deformed face.  Horrified by Jason's hideous features, Trish drops the machete.  Tommy then quickly picks up the machete and swings it into Jason's head.  Jason falls forward and the machete goes deep into the eye socket of Jason, supposedly killing him.  Tommy and Trish embrace that he is dead and they have survived, but Tommy looks down to see Jason's fingers twitching, indicating signs of life.  Tommy, in a rage, grabs the machete and begins to hack at Jason repeatedly, screaming out "DIE!  DIE!  DIE!", as Trish screams out Tommy's name hysterically.
The film then cuts to Trish in the hospital, talking to a doctor.  Tommy then comes in, and in a brother-sister moment, would embrace each other and hug, only for Tommy to look over Trish's shoulder into the camera with an evil stare, as the film ends and goes to credits.
==Alternate Ending==
An alternate ending to the film, included in the 2009 Deluxe Edition DVD, shows a dream sequence where Trish and Tommy wake up the next morning after killing Jason to the sound of police sirens.  Trish sends Tommy to summon the police officers who have arrived next door.  At that point, she notices water dripping from the ceiling and goes to investigate.  She enters the upstairs bathroom and finds the body of her mother, drowned in the bathtub.  At that moment, Mrs. Jarvis's eyes open and Jason appears behind Trish, ready to strike.  Trish then suddenly wakes up in the hospital in a scene reminiscent of the ending of the first movie.  In his commentary, the director, Joseph Zito, says the scene was cut from the film because it interfered with the idea that this would be the final film in the Friday the 13th film franchise.
