[Q]: The plot focuses on a field trip by Professor Ernst Prell to investigate Yeti sightings, along with four graduate students: Keith Henshaw, Karen Hunter, Tom Nash and Lynn Kelly.The night before the trip, the professor invites Keith to dinner at a restaurant, where he samples an exotic dish named "gin sung." The rest of Dr. Prell's students attend an off-campus party where they encounter a former student, turned alcoholic groundskeeper, named Spencer St. Clair, who is there with his wife April. St. Clair proceeds to tell everyone within earshot the story of Prell's last Yeti-seeking field trip, which only he and the professor survived.After the party, Spencer continues to drink, and upon returning home fights with his wife and cuts her throat with an electric carving knife. Afterwards, he climbs into the bathtub fully clothed. He is killed by his not quite dead wife, who drags a toaster into the bathroom and dumps it into the bath, electrocuting him.In the morning, the professor travels by van with his students to Boot Island, where his friend Dr. Karl Werner lives. Werner has recently seen the Yeti on his island, and conjectures that he was marooned there by melting winter ice. He introduces the others to a mute Native American manservant named Laughing Crow. The group have dinner, which is again "gin sung," then go to sleep after one of the students, Tom, sings a song about the Yeti.The next day, the professor and his students begin their search in the woods of the island. Tom sneaks off to go hunting and is killed by the Yeti, a shaggy creature whose loud heartbeat is clearly audible. The rest of the group look for Tom the next morning. Karen finds only his rifle and his severed leg. Meanwhile, Lynn goes into Dr. Werner's greenhouse and sees something that frightens her; she runs into the woods and is also killed by the Yeti.At the house, the remaining students find that the phone is out of order. The professor decides to use Tom's leg as bait to lure the Yeti into a trap. The plan fails, however, as Prell returns to the house claiming he was knocked down by the monster, who escapes with the leg in its jaws. Prell then decides to try again, using Lynn's body as bait. Karen tries to hide the body in the greenhouse, where she discovers the rest of Tom's body, and passes out. When she awakes, Dr. Prell tells her it must have been a dream as she was asleep for quite some time. Karen doesn't believe him leading them all back to the greenhouse where they uncover Lynn's body. "I guess this proves its not Tom," Prell said.Disgusted that Dr. Prell is going to use their friends body as bait, Karen reluctantly agrees to help out by taking photos, under the condition that they leave Boot Island if they succeed or fail. Both Dr. Prell and Keith agree. Karl wishes them good luck.The professor ties Lynn's body to a tree and the trap is set. The Yeti appears and Keith chases it into the woods. He tracks it by the sound of its heartbeat, but makes the discovery that the sound is actually coming from a speaker attached to a tree. Someone knocks him out with a branch.Back at the house, Laughing Crow is shown listening to an LP record of the Yeti's heartbeat. It turns out that Dr. Prell and Werner are cannibals, using the Yeti scam as a way to lure victims, and that the Yeti is actually Dr. Werner in disguise. While Karen is asleep upstairs, Keith returns to the house and discovers Dr. Prell and Dr. Werner discussing what to do with her. Werner thinks they should just kill her, but Prell says that the code calls for no body bruises and that she must be frightened to death. Keith pulls out a rifle and orders both men to put their hands up. They ignore him. He shoots at them, finding out that the shells are blanks. He is then knocked unconscious by Laughing Crow. Still asleep upstairs, Karen wakes to a growling noise. She looks out the window and finds the Yeti running full speed at the house. Karen flees through the house and ends up trapped in a bathroom. She opens a cabinet to find Laughing Crow holding a knife, and dies of fear. While setting up for their big breakfast, Keith wakes up and manages to sneak away. He tries to escape in the van,but it gets stuck in the mud while trying to hide from the party guests funeral procession. Keith then hoofs it down to the bridge where he manages to flag down a cop who takes him back to the house. At the breakfast, Prell and Werner salute the party guests and hosts, toasting the previous schemes which have provided victims. Keith returns with a local policeman, only to find out that he too is a cannibal. Prell and Werener explain that the "gin sung" Keith has eaten is actually human flesh, and they invite him to join their cannibalistic society. They bring in Karen's body, and Laughing Crow, brandishing an electric carving knife, speaks for the first time, saying "Mr. Henshaw â white meat or dark?" Keith drools. The film ends., Question: Who knocks Keith unconscious?
[A]: Answer: Laughing Crow


[Q]: Professor Norihasa Omori (Atsushi Haruta) visits a local hotel and films himself killing eleven of the hotel guests, employees, his own children before committing suicide, all as part of his wish to understand reincarnation. Since then, the footage of the murders disappears. Thirty-five years later, horror movie director Ikuo Matsumura (Kippei Shiina) decides to make a film about the massacre. As the date of the shoot draws near, Nagisa Sugiura (YÅ«ka), the actress who is set to star as Omori's daughter Chisato (Mao Sasaki), is haunted by the ghosts of the victims. She begins hallucinating and is plagued by nightmares of the killings.Yayoi Kinoshita (Karina Nose) wakes up in the middle of a psychology class, in which the professor publicly opposes the ideas of reincarnation and cryptomnesia. She decides to write an essay supporting cryptomnesia and meets Yuka Morita (Marika Matsumoto), an actress who auditioned for Ikuo's movie. Yuka says she remembers things in a "past life" of hers and shows Yayoi a birthmark that would appear to be evidence of strangulation, which reveals that she has the same vision as Nagisa."[2] Yayoi and Yuka check out the college library, but mysterious forces drag Yuka away.Meanwhile, Nagisa begins to believe that she is the reincarnation of Chisato Omori. However, during another hallucination, she discovers Yayoi in the cubby where the little girl was slain. Realizing that she is not the real reincarnation of Chisato, Nagisa witnesses the actors (who are appearing as their reincarnations, which they are to portray) being drawn back to the places where they died. With all the victims walking towards her, Nagisa becomes aware of the truth: she is the reincarnation of the homicidal professor. Pursued by the ghosts, Nagisa is forced to reenact the professor's suicide, but survives.Sometime later, in a mental ward, Nagisa - bound in a full-body wrap - is still haunted by the souls of Omori's children. Ayumi Omori (Miki Sanjo), the professor's wife, gives Nagisa her children's favourite toys (which is a ball and a doll).

[A]: Answer: Nightmares of the killings


[Q]: At the beginning of winter, everyone prepares for the final season of the year. Out of curiosity, Tinker Bell wants to go to the Winter Woods. The tinker fairies make snowflake baskets which are delivered by snowy owls. Later that day, she helps Fawn take the animals to the Woods to hibernate. While Fawn is busy, Tink crosses the border, and her wings start to glow. Seeing this, Tink is convinced that she is meant to explore the Woods. But Fawn warns her that her wings are freezing and rushes her to the fairy hospital. After being examined, she remains curious about her wings. Tink then flies off to the Book Nook, where she finds a book on Wingology, but finds the page on "Sparkling Wings" chewed up by bookworms. A reading fairy tells her that the Keeper, the author who lives in the Winter Woods, might be able to help her.Preparing herself and using the final shipment as her only chance, she sneaks into the workshop and climbs inside one of the baskets. She gets picked up by a novice owl and makes her way across the border. The owl then accidentally drops the basket, and she crashes into the snow. Realizing her book has been flung from her bag, she tries to get it back. However, Milori, the Lord of the Woods, finds the book and asks Sled to return it to the Keeper. Tink then follows him to the Winter Library. Upon arriving, she spots the Keeper, Dewey. But before she can talk to him, another winter fairy rushes into the room and proclaims that her wings sparkled the day before. Tink meets the fairy, whose name is Periwinkle. Suddenly, the girls' wings start to glow. Astonished, Dewey brings the two to a platform and positions their wings before the whole chamber becomes filled with images explaining their origins: that Tinkerbell and Periwinkle were born of the same baby laughter. The two then realize that this would make them sisters. Suddenly, Lord Milori arrives, concerned about the book, warning him to send any warm fairy back. Dewey tells the two they can spend a day together before Tink has to return home.Periwinkle shows Tink her world, meeting Peri's friends and spending the day together. That night at Peri's home, as Tink builds a fire, she realizes that if she can make it warm there, she can, in turn, make it cooler at her home. Suddenly, the floor melts beneath them. Seeing this, Dewey tells them that Tink has to go home. She then comes up with a plan. When they reach the border, she tells Peri to meet her at the border tomorrow. When Tink arrives home, she asks Clank and Bobble for help, and they bring her other friends to help. The next day, Tink arrives at the border with Bobble and Clank, pulling along a snow-maker. Now able to keep her cold enough, Peri crosses the border to the warm side of Pixie Hollow. She meets Tink's friends and continues her tour. After a while, Tink then notices Peri's wings wilting; the machine is running out of ice. They then return to the border. Lord Milori appears and instructs Peri on how to fix her wings. Queen Clarion also arrives and sadly explains that they can never see each other again.As the girls leave, the machine gets knocked by Milori into the stream and creates a massive snowstorm. Later that day, Queen Clarion tries to explain to Tink why the rule is important, as does Lord Milori with Periwinkle. They are told the story of two fairies, one warm and the other a winter fairy, who met and fell in love. As their romance grew stronger, they disregarded the dangers across the border. Sadly, one of them broke a wing, for which there is no cure. From that day, Queen Clarion realized that some fairies should remain apart. Meanwhile, the trapped snow-maker begins to freeze the Autumn Woods. They, along with Tink's friends and the Ministers, arrive at the stream and find Clank and Bobble attempting to free it. They succeed, but a freeze is coming. Queen Clarion tells everyone to save the tree for the freeze will kill it, eternally stopping the flow of pixie dust. They try everything they can to save the tree. Tink then notices that a Periwinkle that Peri had covered in frost is still alive, despite its cold surroundings. She flies to the Winter Woods but, on her way, falls into the snow. She then asks Peri and her friends about the frost around the flower, and Gliss explains that frost acts like a blanket, keeping the warm air inside. This gives Peri the idea that they could frost the tree before the freeze comes, and they then head to the tree. Meanwhile, at the tree, their plan is failing to the Queen's disappointment, but then Tink and the others arrive. They explain the power of their frost, but Spike realizes that the tree is too big for three of them to finish in time. The rest of the frost fairies then arrive to help. Accomplished of frosting the whole Hollow, Milori states that they've done all they can. He then warns the warm fairies that the freeze is upon them and they must take cover, including the Queen whom he gives his cape to, revealing his broken wing and that he and Queen Clarion were the fairies in the story. He then orders all the winter fairies to stand guard all over the tree.Some time later, the freeze begins to melt and pixie dust begins to flow again. All the fairies celebrate. However, Tink reveals that she broke a wing when she flew to the Woods and warns Periwinkle to go back before her wings wilt. As the twins hold hands and say goodbye, they touch their wings and blindingly white light bursts from their wings, which slowly heals Tink's broken wing. In an epilogue, it is shown that warm fairies now cross over into the Winter Woods and that the two "seasons" now interact and become good friends, even lovers., Question: What would happen if the tree dies?
[A]:
Answer: The flow of pixie dust would end.
