Answer the following question: Generate a question about the following movie plot: As a young child, Tina Shepard witnesses 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, now a teenager, is still struggling with the guilt surrounding the death of her father. Tina's mother, Amanda, 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 to the dock thinking about her father's death. While thinking about him, she wishes he would come back. Instead, Tina's psychic powers 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 emerges from the lake and his reign of terror descends on the area once again. Next door to the Shepard residence is a group of teens who are throwing a birthday party for their friend Michael: preppy Russell and his girlfriend Sandra, Ben and his girlfriend Kate, science fiction writer Eddie, stoner David, perky Robin, shy Maddie, and snobby socialite Melissa. Michael's cousin Nick, who has arrived just for the party takes a liking to Tina, much to the jealousy of Melissa, who bullies Tina. Tina tells Nick about Jason and has a vision of Jason murdering Michael. Meanwhile, Jason kills Michael in real life, along with Jane, and later kills another couple camping in the woods. While Tina goes off to find her mother and Nick goes with her, Jason proceeds to kill the other teens. Russell is killed with a hatchet to the face, and Sandra is pulled underwater while she is skinny-dipping. Jason stalks Maddie and kills her in the barn with a scythe, and then crushes Ben's skull with his bare hands before shoving a party horn...
