Example Input: In the Spanish countryside, a middle-aged man named Hector (Karra Elejalde) and his wife (Candela Fernandez) live in a home that they are renovating. Hector scans the forest behind their house with binoculars and sees a young woman take off her t-shirt, exposing her breasts. When his wife goes shopping, he investigates and finds the woman on the ground, naked and unconscious. He is then stabbed in the arm by a mysterious man with pink bandages on his face. Fleeing and breaking into a mysterious nearby building, Hector contacts a scientist (Nacho Vigalondo) by walkie-talkie, who warns him of the bandaged man and guides him to his location, promising safety. The scientist convinces Hector to hide from the bandaged man, who is just outside, in a large mechanical device. However, when he leaves the machine, Hector discovers that he has traveled approximately an hour back in time.The scientist explains that the machine is an experimental time travel device, and refers to Hector as "Hector 2". The scientist tells him that they need to stay where they are and let events unfold. Despite the scientist's warning, Hector 2 drives off in a car, passing a cyclist, only to be run off the road by a van, cutting his head, which he wraps using the bandage from his arm wound. The bandage turns pink from absorbing the blood. The cyclist approaches to see if he is all right - it is the woman he earlier saw in the forest. He proceeds to replicate events by making her undress in view of Hector 1. When she runs away, he catches her, inadvertently knocking her out. He lays her out naked on the ground and then stabs Hector 1 in the arm when he arrives. The woman escapes. Hector 2 returns to his home, where he hears a scream and chases a woman through his house and onto the roof. When he attempts to grab her, she slips and falls to her death. Seeing the body from the roof, Hector 2 is horrified, believing he has killed his own wife.Hector then contacts the scientist over a walkie-talkie and convinces him to lure Hector's past self to the lab with warnings that he is being pursued. Driving to the lab, Hector 2 insists that he must travel back one more time, despite the scientist revealing that there is a Hector 3, who told him he must stop Hector 2 from doing just that.After removing his bandages, Hector 3 convinces the scientist to send him back several seconds before Hector 2 appears. He finds a van and runs Hector 2 off the road, but crashes as well, knocking himself out. Upon waking, he informs the scientist he has failed and to stop Hector 2 by any means. He encounters the woman again, startling her into screaming, though she does not recognize him as her assailant. Since Hector 2 has heard her scream, Hector 3 and the woman flee to Hector's house. They become separated. Hector 3 finds and hides his wife, then realizes what has to happen / will happen / has already happened. He finds the woman, cuts her ponytail off, gives her his wife's coat, and tells her to hide upstairs. Hector 2 chases her onto the roof. Hector 3 sits on his lawn with his wife, as Hector 2 accidentally kills the woman, then drives off. Emergency vehicles are heard approaching in the distance., Question: Who contacts the scientist over a walkie-talkie?
Example Output: Answer: Hctor

Example Input: Dr. Carter Nix (John Lithgow) is a respected child psychologist. His wife, Jenny (Lolita Davidovich), becomes concerned that Carter is obsessively studying their daughter, Amy; he regards her like a scientist tracking the development of his creation. But Carter himself suffers from multiple personality disorder consisting of Cain, a street hustler, Josh, a shy 10-year-old boy, and Margo, a middle-aged nanny. Carter and Cain are killing young mothers to procure their children for his experiments.Jenny is having an affair with Jack Dante (Steven Bauer), the widower of a former patient. She had a relationship with him years ago, but he left her. Now she plans to leave Carter and elope with him. When Carter accidentally discovers their tryst, he descends completely into his madness and begins leaving subtle clues for the police that Jack is the real killer. Next, he attempts to kill Jenny by submerging her car in a lake. She escapes and confronts Carter at home. Unable to find Amy, Jenny demands Carter tell her where she is. Carter replies that she is with his father, whom Jenny knows has been dead for years.Carter is apprehended for attempted murder. The police bring Dr. Lynn Waldheim (Frances Sternhagen) to interrogate him. Waldheim interviews Carter and informs the police that she co-wrote a book with Nix Sr. called Raising Cain, about a boy with multiple personality disorder. Nix Sr. had extensive detailed knowledge of Cain's tortured childhood, including taped recordings of their sessions. However, Waldheim was never allowed to meet Cain. She pieced the situation together: Nix Sr. dispassionately put his own son through years of severe child abuse to gain firsthand accounts of his traumatic psychological development and study the emerging personalities. Horrified, Waldheim quit the project.During interrogation, Margo and Josh act and speak for Carter. Josh recites a rhyme and vanishes, and Margo assumes control. She stonewalls Waldheim from any further questioning. Eventually, Carter and Cain break from their confines. They pounce upon Dr. Waldheim, knocking her unconscious and leaving the building disguised as her. The police soon find Waldheim begging them to arrest Carter before any children are harmed.Nix Sr. (Lithgow) is in fact alive, having faked his own death to elude prosecution for attempting to buy babies. He has established a new identity and a clandestine research facility in Norway. He has been using Carter and his multiples to procure the children so he will have an adequate control group to study the development of MPD. Jenny follows who she thinks is Waldheim to a motel, but it is actually Carter/Cain. She follows Carter/Cain, who is now Margo, into an elevator. When it opens, she sees Nix Sr. with her daughter Amy. While Jenny begs for Nix Sr. to give back her daughter, Carter, Cain and Margo stabs "their" father from behind. Jack arrives with the police, and Carter and his personalities disappear.The movie ends with Jenny and Amy in a park. Amy runs off into the woods calling "Daddy, Daddy". Jenny follows her and finds Amy, who says her father has gone away. When Jenny bends down to pick Amy up, Carter appears behind her in a wig and a dress; Margo is now in control. Jenny holds Amy in her arms, oblivious to who is behind her., Question: What does he need the children for?
Example Output: Answer: Study the development of MPD.

Example Input: In 1957 a Russian cargo plane is flying above Antarctica. In the cargo hold, three Russians sit with a padlocked box. The co-pilot leaves his seat and goes into the cargo hold, then begins to shoot the other men, who return fire. The chaos caused by the gunfight leads to a crash which kills all aboard.In modern times, newcomers arrive at the United States' AmundsenScott South Pole Station in Antarctica, while others who are scheduled to leave are preparing to do so early because of a storm. They must depart before the onset of winter or remain for six months. Deputy U.S. Marshal Carrie Stetko (Kate Beckinsale) has been working in Antarctica for two years, since a betrayal by her partner in Miami that killed him and nearly killed her. She plans to retire after returning to the United States in two days.Stetko, her friend Doc (Tom Skerritt), and pilot Delfy (Columbus Short) fly to the remote Haworth Mesa to retrieve a discovered body. The dead man is Anton Weiss (Marc James Beauchamp), one of a group of three scientists looking for meteorites. An autopsy finds evidence of murder by axe. A murder requires a federal investigation; Stetko considers sending the body to McMurdo Station to avoid spending another winter in Antarctica, but decides to continue the investigation. When Stetko goes to speak to one of the others at Vostok Station, she finds him dying from a neck wound and is herself attacked by a black-clad man with an axe. Stetko injures her hands in escaping, losing the wet skin of her fingers on the metal handle of a door. Later, she finds Robert Pryce (Gabriel Macht), a United Nations security agent, examining the body of the second scientist. They conclude that the third, who is missing, must be the killer and set out to explore the group's most recent search site. There, Stetko falls through the ice to find the old Russian cargo plane. Pryce and Delfy join her to investigate, and they realize that the locked box had been opened and six cylinders removed. Pryce reveals that it is possible that nuclear fuel of interest to arms traffickers may be in the cylinders.After nearly being trapped by a cave-in at the plane, Stetko must have her badly frostbitten fingers amputated by Doc. She then finds the missing scientist hiding in her office. He tells her that he and his two companions found the plane and took the canisters, but the killer has them now. Before Stetko can protect him he is killed, but Carrie captures his killer, who is revealed to be Australian biologist Russell Haden (Alex O'Loughlin). The base commander orders everyone to evacuate because of the murders. With Haden locked in the brig and the winter storm near, Stetko and Pryce search for the canisters.Stetko checks the last departing plane's cargo manifest and learns that the bodies of the dead scientists were not aboard. She searches their body bags and notices that the stitching on Weiss's old wound matches the distinctive pattern on her amputated fingers. Stetko explores the body and finds several bags of large, uncut diamonds. Doc confesses that he was part of a diamond smuggling ring with the others before Haden killed the rest. He had hoped that the diamonds would make him wealthy outside Antarctica. When Doc tells Stetko he wants to see the aurora australis one last time, she allows him to walk outside to his death.Six months later, Stetko, Pryce, and Delfy have wintered at the facility. She transmits an email to her superior, rescinding her previous resignation and asking for a warmer location for her assignment., Question: Who was almost trapped by the cave in?
Example Output:
Answer: Doc
