There’s a legend ’round here. A killer buried, but not dead. A curse on Crystal Lake. A death curse. Jason Voorhees’s curse. They say he died as a boy, but he keeps coming back. Few have seen him and lived. Some have even tried to stop him. No one can. People forget he’s down there… waiting.
It is the beginning of the Kane Hodder era of Jason with the film kicking off months after the conclusion of the previous film, 7-year old Tina Shepard hears her alcoholic father physically abusing her mother. The emotional trauma unlocks Tina’s previously latent telekinetic powers, which result in her father’s death at the bottom of Crystal Lake.
Ten years later, Tina is still struggling with the guilt surrounding the death of her father. Tina’s mother, Amanda Shepard, takes her to the same lakeside residence so that her powers can be studied (and unknowingly exploited) by her psychiatrist, Dr. Crews. Dr. Crews begins a series of experiments (verbal assaults) designed to agitate Tina’s mental state, forcing her powers to become more pronounced.
After a particularly upsetting session with Dr. Crews, Tina runs from the cabin and runs to the dock thinking about her father’s death. While thinking about him, she accidentally breaks the chain around the neck of Jason Voorhees, the undead Crystal Lake serial killer. Tina’s torment from her powers is increased as Jason’s reign of terror descends on the area once again. Mrs. Shepard, Dr. Crews, and a group of youths vacationing in a nearby cabin are all violently killed by Jason.
The now-orphaned Tina is left with no choice but to utilize her telekinesis in an effort to stop him. She unleashes her powers in various ways such as forcing Jason’s mask to tighten until it breaks in two, revealing his decaying and deformed face. As the battle rages on the Shepard lakeside cabin is destroyed by an explosive fire. Although she is unable to kill Jason, she unknowingly resurrects the spirit of her father, who emerges from the lake and drags Jason back down into the depths with him, chaining the killer once more.
