Friday the 13th Part VII: The New Blood

After witnessing her alcoholic father John physically abusing her mother Amanda, a young Tina Shepard attempts to escape the chaos at home and heads out onto Crystal Lake in a boat. When John follows her in an attempt to stop her, Tina's dormant telekinetic abilities emerge, and she accidentally destroys the dock John is standing on, causing him to fall into the lake and drown. Years later, a teenage Tina is still struggling with remorse surrounding John's death. Amanda takes her to the same lakeside residence as part of her treatment from her psychiatrist, Dr. Crews. He begins a series of experiments (verbal assaults) designed to agitate Tina's mental state, forcing her powers to become more pronounced. While Dr. Crews claims to be treating Tina, in reality, he is only trying to exploit her psychic powers. After a particularly upsetting session with Dr. Crews, Tina runs from the cabin and to the dock thinking about John's death. While thinking about him, she wishes he would come back. Her powers unwittingly awaken mass murderer Jason Voorhees, who had been chained to the bottom of Crystal Lake by Tommy Jarvis seven years prior, and he emerges from the water to commit another killing spree. Next door to the Shepard residence is a group of teens who are throwing a birthday party for their friend Michael Rogers. The group includes Michael's cousin Nick, preppy Russell and his girlfriend Sandra, Ben and his girlfriend Kate, science-fiction writer Eddie, stoner David, perky Robin, shy Maddy, and snobby socialite Melissa. Nick, who has arrived just for the party, becomes attracted to Tina, much to Melissa's chagrin. Melissa attempts to break up Nick and Tina, even going as far as kissing Eddie to make Nick jealous, but her schemes are to no avail – other than making Eddie feel spurned thereafter. Tina tells Nick about Jason and has a vision of him murdering Michael. Meanwhile, Jason kills Michael and his girlfriend Jane McDowell, later murdering Dan Carter and Judy Williams, another couple camping in the woods, as well. When Tina goes off with Nick to find Amanda, Jason proceeds to kill the other teens one by one. Russell and Sandra go to the lake for a swim. While Sandra goes skinny-dipping, Russell is killed with an axe to his face. Sandra discovers his body before she is pulled under the water and drowned. Maddy goes looking for David but finds Russell's body. She runs for help, but Jason attacks her in a nearby barn and kills her with a sickle. Jason then kills Ben by crushing his skull and then Kate by driving a party horn into her eye. Inside the house, Jason stabs David and slices Eddie's neck open. Upstairs, Robin finds David's severed head and is defenestrated to her death. When Jason attacks Dr. Crews, he saves himself by using Amanda as a human shield, but Jason eventually kills him with a brushcutter. Tina finds Amanda's body shortly afterward and uses her powers to electrocute Jason and crash part of the house down onto him. When Nick and Tina try to tell Melissa what happened, she thinks that they are crazy and tries to leave, but Jason kills her with an axe to the face. Nick tries to fight off Jason, but he is quickly subdued. Tina unleashes her powers, breaking Jason's mask and exposing his disfigured and decomposed face. As the battle rages on, the Shepard lakeside cabin is destroyed by an explosive fire and the attack continues on the dock. Although Tina is unable to kill Jason, she focuses and summons the spirit of her father, who rises from the lake and drags Jason back down with him into the depths of Crystal Lake, chaining the serial killer once more. The following morning, Tina and Nick are taken away in an ambulance. A firefighter finds Jason's broken mask in the wreckage, and the screen fades to black as Jason's whispers can be heard in the distance.
