The movie opens on the single survivor from the first film, Alice. She has been trying to recover from the events of the first film, living quietly by herself. While preparing dinner Alice opens her fridge, and is shocked to see Pamela Voorhees' head sitting in there.. As she backs away from the fridge an ice pick is driven through her skull by someone, killing her.
Next we see a group of counselors arriving at a brand new camp, opening near the now condemned Camp Crystal Lake, as part of a counselor training session. On the first night the counselors sit around a fire while Paul Hault, the training supervisor, tells them the story of Jason Voorhees. How Jason drowned in Crystal Lake and his mother Pamela went insane with grief, driving her to commit the murders of "Camp Blood". When the story is over, Ted jumps out of the woods wearing a monster mask and holding spear to scare the other counselors. Paul reassures everyone by saying Jason is dead.
I'll just check out this ominous shack by myself.
Crazy Ralph, from the first film, is spying on Paul make out with another supervisor, Ginny, when he is grabbed from behind by an unseen assailant and strangled with a garrote. Next morning, the counselors Jeff and Sandra decide to sneak into the old Crystal Lake campgrounds. After finding a dead dog, a police officer appears and tells them to stay away from the camp. While driving away, the police officer sees a strange man running across the road into the forest. Chasing after him, the officer finds a rundown old shack deep in the woods. He enters the shack and is shocked by what he finds, but the viewer is left in the dark, as the the officer is bashed on the head from behind with a hammer.
The counselors begin their training exercises, and later that night decide to party. Most of the counselors leave the campground, but 6 remain behind to do their own partying. Terry goes skinny dipping, not knowing that Scott is following her. Scott her steals her clothing while she is in the water and runs away with them, but gets lifted off the ground when he steps in a rope trap. Terry laughs at him and goes to retrieve a knife from the cabin to cut him down. But when she returns Scott is dead with a slit throat, and Terry is killed while running away.
Mark, wheelchair bound, is hanging out with Vickie when she tells him she needs to go back to her cabin for something. It starts to rain, and when Vickie does not return Mark goes out to investigate. While wheeling toward her cabin, he is chopped in the face by a machete and killed. The unseen killer then rolls him down stairs leading to the lower cabins.
The brutal consequences of premarital sex.
The killer enters the cabin Mark was in, the main cabin, where upstairs Sandra and Jeff are making sweet premarital love. The killer takes a spear, left behind by Ted earlier, and goes upstairs. Sandra does not notice the killer until he is standing right above them, and she tries to force Jeff off. Then, in one of the most famous slasher film killings (and a total ripoff of Bay of Blood), they are impaled by the spear while still in the missionary position. Vickie finally returns from her cabin and calls out to her friends. She enters Jeff's room and looks under the bed covers, but is surprised by killer hiding under them. Vickie is slashed in the leg as she tries to escape, then stabbed in the chest with a large knife.
Jason gets hot under the collar, or hood.
Ginny and Paul return from town and enter the main cabin, where they find none of the lights are working. As they search the cabin Paul is attacked by the killer, who is wearing a potato sack over his head. Ginny panics and runs, jumping through a window after she finds Ralph's corpse. She runs through the woods and finds the old cabin from earlier. She decides to look in the cabin for anything helpful, but she finds what shocked the police officer. On a dirty altar deep in cabin is placed the severed head of Pamela Voorhees. Surrounding the altar are the mutilated corpses of the killer's victims, including the body of Terry. Ginny realizes who the killer is: Jason Voorhees. Jason did not drown in Crystal Lake, but dragged himself into the woods where he has lived as a hermit for 24 years. Jason was watching from the woods when Alice beheaded his mother, and the anger drove him into a murderous frenzy. Ginny decides to trick Jason and puts on Pamela's sweater. Jason is fooled into believing Ginny is his mother, long enough so that Paul can arrive and tackle him. While Jason is on the ground Ginny picks up his machete and hacks into his shoulder, killing him, or so they think.
Ginny returns to the main cabin with Paul to phone the police. But when they think all is well Jason bursts through a window, the potato sack gone revealing a horribly deformed face, and grabs Ginny. Ginny wakes up later on a stretcher, and as she is carried away she screams Paul's name, but he is never seen again.
Phantom killer (left), Jason (right)
Jason does not wear his iconic Detroit Red Wings hockey mask in Part 2, and doesn't until half way through Part 3. In this film Jason wears a small potato sack with a single eye hole cut out. The potato sack mask was inspired by the Phantom Killer, the real life serial killer of the Texarkana Moonlight Murders. The film based on the Texarkana murders, The Town that Dreaded Sundown, came out only 5 years before Friday the 13th: Part 2, further explaining its impact on the choice of Jason's mask.
Steve Daskawicz, who played Jason, had a lot trouble with the mask. In the scenes where Jason runs through the woods, the potato sack would constantly flop around so Steve could not see where he was going. The special effects artists got the idea to tape the mask in place with double-faced tape. It helped, but Steve developed painful burns from the tape when he removed the mask.
What is arguably the most well known kill in the Friday the 13th franchise: when Jeff and Sandra are double penetrated (hehe) by a spear, does not actually appear in any version of Friday the 13th Part 2. The full sequence in which the two bodies are shown impaled, with Sandra struggling to free herself, was cut by the MPAA to avoid an X rating. However a picture of the scene remained on the back of the original VHS case.
The scene was done by attaching a fake latex back filled with blood syrup to Bill Randolph (Jeff), which was then pierced by a real spear to spill the blood. Marta Kober (Sandra) was not even on the bed, instead she stuck her head through a hole made in the bed to give the illusion of lying under Jeff.
Alice: Stabbed in the temple with an icepick after she discovers Pamela Voorhees' head in her fridge.
Crazy Ralph: Strangled with a garrote as he spies on Ginny on Paul.
Police Officer: Gets a claw hammer to the back of the head when he investigates Jason's shack.
Scott: Gets his throat slit with a machete as he hangs upside down in a rope trap.
Terry: We don't actually see her die, but we can assume she is stabbed after finding Scott's corpse. Later her body is seen in Jason's shack.
Mark: Gets a machete slammed into his face. He is then pushed, wheelchair and all, down a flight of of stairs. Poor guy.
Jeff: A spear is thrust into his back as he lies on top of Sandra.
Sandra: Impaled along with Jeff.
Vickie: Gets her leg cut open when she discovers Jason, then is forced into a corner and stabbed in the chest with a large kitchen knife.
See Terry's body in the lower left?
Paul: His death is debatable, as the only indication we have is Ginny calling his name at the end of the film. BUT, in a deleted ending sequence, the severed head of Pamela Voorhees opens her eyes and smiles as Ginny calls his name, indicating that Jason did a good job for mother (by killing Paul).
