Task: Question Generation
Input (English):  In summer of 1958, Barry and Claudette, two Camp Crystal Lake counselors, sneak into a storage barn to copulate. Before they can engage, an unseen assailant enters and murders them.
21 years later, Annie Phillips enters a small diner and asks directions to the reopened Camp Crystal Lake. Enos, a truck driver agrees to drive Annie halfway. An elder named Ralph reacts to this by warning Annie that the camp has a "death curse". During the drive, Enos explains that a young boy drowned at Crystal Lake in 1957, and the incident the following year. After Enos drops her off, Annie hitches a ride, but the second driver then chases her into the woods and slashes her throat.
At the camp, counselors Ned, Jack, Bill, Marcie, Brenda and Alice and owner, Steve Christy refurbish the cabins and facilities. As a storm ensues, Steve leaves campgrounds to stock supplies. Soon, the killer arrives and begins to kill the counselors, including Steve. Worried, Alice and Bill, the only two left, leave the main cabin to investigate only to discover a bloody axe in Brenda's bed, the phones disconnected, and the cars inoperable. When the power goes out, Bill goes to check on the generator and is killed. Alice then heads outside and calls out for him and finds his dead body pinned to the back of the door. She screams and flees back to the main cabin to hide.
Alice sees a vehicle pull up; thinking its Steve, she rushes out but sees a middle-aged woman named Pamela Voorhees, an "old friend" of Christy's. As Alice tries her news, Pamela reveals herself the mother of the drowned boy - Jason, blaming his death on the counselors having sex. She reveals herself the killer when she violently rushes toward Alice with her knife. A chase ensues with Mrs. Vorhees attempting to kill Alice, but she escapes to the shore. Just as she eases, Pamela attempts to kill her again. During the final struggle, Alice decapitates her with a machete.
Afterwards, a shaken Alice boards and falls asleep inside a canoe and floats to Crystal Lake's middle. Just as Alice sees police arriving, a decomposing body drags her underwater. She then awakens in a hospital screaming. A police officer tells her the aftermath. When she asks about Jason, the officer replies with no evidence of any boy; Alice says "He's still there". The film ends with a peaceful shot of Crystal Lake.
