Friday the 13th is a horror game based on the famous film series of the same name of American cinema. The content of this work is about a crazy serial killer named Jason Voorhess.
When Jason was 11 years old, he contracted a strange disease, which made Jason's head bigger than normal children. One day Jason was teased by a bunch of kids, pushing into Crystal Lake. Due to swimming, Jason was drowned right under the lake. Pamela picked up her son's body, she read a spell rescued Jason, the same curse that will help Jason become immortal later.
From that day forward, Pamela was angry and planned to kill anyone who dared to come to the Crystal Palace because the tourists had hurt her son. Many years later, Jason's mother killed many people to camp here. However, in one action, Pamela failed and was killed by a female victim named Alice Hardy.
Following the events of the previous film, a badly wounded and unmasked Jason Voorhees goes to a lakefront store for a change of clothes. While there, he murders the store owners. Harold is killed with a meat cleaver slammed into his chest, and his wife Edna is impaled through the back of the head with a knitting needle. Meanwhile, Chris Higgins and her friends travel to Higgins Haven, her old home on Crystal Lake, to spend the weekend. The gang includes pregnant Debbie, her boyfriend Andy, prankster Shelley, his blind date Vera (who does not reciprocate his feelings) and stoners Chuck and Chili. After running into a man named Abel, who warns them to turn back, the gang meets Chris' boyfriend Rick at their destination.
At a convenience store, Shelley and Vera get into a confrontation with bikers Ali, Fox, and Loco. Shelley gets in the car and knocks down their motorcycles, impressing Vera. Later, the bikers show up at Higgins Haven, where they take the gas out of the van and attempt to burn the barn down to get even. Jason, who has been hiding in the barn, murders Fox and Loco with a pitchfork before beating Ali unconscious with a pipe wrench. That night, Chris and Rick head out into the woods. Chris tells Rick the main reason she returned is to confront her fears, and she explains about how she was attacked by a deformed man two years earlier, causing her to leave Crystal Lake in order to escape the trauma.
Back at Higgins Haven, a scorned Shelley scares Vera with a hockey mask and then wanders into the barn where Jason slashes his throat and takes his mask. Now with his disfigured face concealed, Jason emerges from the barn and proceeds to murder the rest of the group. Vera retrieves Shelley's wallet from under the dock and is shot with a speargun. Jason then enters the house and slices a head-standing Andy in half with a machete. Debbie has a knife shoved through her chest while resting on a hammock. When the power goes out in the house, Chuck goes downstairs to the basement where Jason hurls him into the fuse box, electrocuting him. Chili is then impaled with a hot fire poker. When Rick's car dies, Chris and Rick are forced to walk back to the house to find it in disarray. Rick steps outside to search the grounds, but Jason grabs him and crushes his skull with his bare hands.
Jason then confronts Chris, who narrowly escapes the house and tries to flee in her van. The van breaks down and Chris makes her way to the barn to hide, but Jason attacks her again. Inside the barn, Chris hangs Jason. As he unmasks himself temporarily, Chris recognizes him as the man who attacked her two years ago. A revived Ali tries to attack Jason, but he is quickly dispatched. The distraction allows Chris to strike Jason in the head with an axe. Jason staggers momentarily towards her before collapsing. Exhausted, Chris pushes a canoe out into the lake and falls asleep.
Chris has a nightmare of Jason running towards her from exiting the house, and of the decomposing body of Pamela Voorhees - her head reattached - emerging from the lake and pulling her in. The following morning, the police arrive and escort a traumatized Chris from Higgins Haven. Jason's body is shown to still be lying in the barn as the lake is shown at peace once again.
