question:
Two North Korean soldiers are killed in the DMZ at a North Korean border house, before Sergeant Lee Soo-hyeok (Lee Byung-hun), a South Korean soldier on border duties, attempts to flee back to the South Korean side. The southern troops rescue him while the gunfire erupts and, two days later, the fragile relationship between the two Koreas depends on a special investigation conducted by Swiss Army Major Sophie E. Jean (Lee Young-ae) on behalf of the Neutral Nations Supervisory Commission.As Sergeant Lee Soo-hyeok has confessed to the shootings, Sophie investigates why the two Koreas have contradicting accounts of events; Soo-hyeok's states he was knocked out and kidnapped while relieving himself and, waking tied up in the North Korean border house, secretly freed himself and shot three North Korean soldiers, leaving two dead. The North Korean survivor Sergeant Oh Kyeong-pil (Song Kang-ho) states that Soo-hyeok barged into the border house and shot everyone before retreating when the wounded Kyeong-pil returned fire.The autopsy report shows that one soldier, Jeong Woo-jin (Shin Ha-kyun), was shot eight times repeatedly, indicating a grudge was held; additionally, a single bullet is not accounted for. Over the course of the investigation, witness Private First Class Nam Sung-shik (Kim Tae-woo) attempts suicide by jumping out of the window of the interrogation room and a strange emotional reaction between Kyeong-pil and Soo-hyeok during a meeting causes Sophie to confirm her suspicions that the surviving soldiers and Woo-jin held a mutual friendship and were attempting to protect one another.Explained through flashbacks it is shown that Soo-hyeok was on patrol with other soldiers, only to get lost on the North Korean side and to partially trip a mine; found by Kyeong-pil and Woo-jin, the two deactivate the mine, which later prompts Soo-hyeok to throw written messages over the border to maintain contact. Eventually inviting Soo-hyeok across the border, the three become a group of friends that soon includes Sung-shik, with the four agreeing to leave politics out of their friendship so to remain loyal to their own country.As tensions rise between the North and South, Soo-hyeok and Sung-shik return to the North to say goodbye and celebrate Woo-jin's birthday, only to be discovered by a commanding officer from the North and resulting in a Mexican Standoff. Despite Woo-jin panicking and betraying his friends, Kyeong-pil convinces Woo-jin, Soo-hyeok and the officer to lower their weapons, only for Sung-shik to panic and shoot the commanding officer when he reaches for his radio; when Woo-jin draws his gun again, Sung-shik shoots him, and in a daze shoots his corpse several times. Earlier in their friendship when Soo-hyeok is joking around with his gun, Kyeong-pil asked Soo-hyeok if he'd ever had to kill a man like he's had to, implying that Soo-hyeok doesn't know what it's like. Kyeong-pil slaps Sung-shik out of his daze, takes the gun from him and kills the still-alive officer, then persuades Soo-hyeok and Sung-shik to flee with a false alibi of being kidnapped, before throwing away the evidence that he and Woo-jin were fraternizing with Southern soldiers. After shooting Kyeong-pil in the shoulder to complete the alibi, Soo-hyeok and Sung-shik flee across the border, with the latter getting past unseen; as Soo-hyeok's wounded leg from the firefight prevents him from running, he is the only soldier seen and picked up by soldiers.Sophie is eventually removed from the case when it's discovered that her father, a former POW, had North Korean ties during the Korean War, thus technically making her a non-neutral. Before leaving, she attempts to informally learn of the true events first with Kyeong-pil and then Soo-hyeok. Having asked Kyeong-pil if he had a message for Soo-hyeok, Sophie gives Soo-hyeok the lighter he first gave to Kyeong-pil. Before saying goodbye and wishing him well, she reveals that Kyeong-pil told her that he saw Soo-hyeok's gun actually shot Woo-jin first during the chaos before Sung-shik shot him. On his way out, Soo-hyeok steals an officer's pistol and commits suicide out of guilt for Woo-jin's death and Sung-shik's suicide attempt. The film concludes with an American tourist's photograph of the joint security area that accidentally contains all four soldiers prior to the incident., Question: Who has suspicions that the surviving soldiers and Woo-jin held a mutual friendship and were attempting to protect one another?
answer:
Answer: Sophie

question:
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: How many Hctors are mentioned here?

question:
The aftermath of a Jigsaw game is discovered by a SWAT team. The victim, Troy, was meant to rip chains from his body in order to escape from a bomb. Lieutenant Daniel Rigg calls Detectives Mark Hoffman and Allison Kerry to the scene. Kerry, who is guilt-ridden over the disappearance of Eric Matthews, points out that the room's only exit was welded shut, breaking Jigsaw's modus operandi of giving his victims a chance to survive. That night, while reviewing the videotape, she is abducted and awakens in a harness that is hooked into her ribs. She manages to retrieve the key from a suspended beaker of acid and unlock it before the timer expires, but it tears her rib cage apart anyway, killing her.Now bedridden from cancer, John Kramer instructs Amanda Young to abduct Dr. Lynn Denlon from her hospital. She is brought to Kramer and instructed to keep him alive until the other victim has completed his game. As Kramer explains the rules, Amanda locks a collar around Lynn's throat that connects to Kramer's heart rate monitor and will detonate if Kramer dies or Lynn moves out of range. The other victim, Jeff, awakens in a box in an abandoned meatpacking plant and learns from a microcassette recorder that he must undergo tests which will lead him to "the man responsible for the loss of his child". Jeff has become unstable and vengeful in the three years since his son Dylan was killed by a drunk driver, and is now estranged from his wife and neglects his daughter Corbett.Jeff's first test leads him into a meat freezer. He finds Danica Scott, the only witness of Dylan's death, who refused to testify in court; she is naked and chained at the wrists between two poles which begin spraying ice-cold water at random intervals. She manages to convince Jeff to help her, but freezes to death before he can retrieve the key. His second test leads him to a vat, at the bottom of which Judge Halden, who gave Dylan's killer six months in jail, is chained at the neck. The vat slowly fills with liquefied pig corpses, but Jeff reluctantly incinerates Dylan's belongings in order to retrieve the key and save Halden. His third test brings him before Timothy Young, Dylan's killer, who is strapped to a machine that will twist his limbs and neck in turn until they break. The key is tied to the trigger of an enclosed shotgun. Jeff eventually tries to free Timothy, but taking the key discharges the shotgun and accidentally kills Halden, and Jeff is unable to stop the machine before Timothy's neck breaks.During an improvised surgery, in which Lynn removes a piece of Kramer's skull to relieve pressure on his brain, he hallucinates about another woman and declares his love out loud, distressing Amanda. She leaves, and flashbacks show her time with Kramer, as well as her abduction of Adam, which left her guilt-ridden to the point she gave him a mercy killing out of guilt some time after his game. In the present, she reads a letter addressed to her which drives her to hysterics. As Lynn confesses to Kramer that her ordeal has given her new appreciation of her family, Amanda returns with the news that Jeff has completed his tests, but refuses to remove Lynn's collar. She reveals that she no longer believes in Kramer's philosophy, and has designed her traps simply to kill, including Troy's and Kerry's. She also fought with Eric Matthews after he escaped the bathroom by breaking his foot; she implies killing him, but Kramer believes she left him to die.Refusing to listen to Kramer's warnings, Amanda shoots Lynn in the back just as Jeff arrives. He retaliates by shooting Amanda in the neck with a gun provided by Kramer during his tests. As Amanda slowly dies, Kramer reveals that Lynn's test was actually hers: aware of her modus operandi, and unwilling to allow a murderer to inherit his legacy, he decided to test "her will to keep someone alive"; to this end, he told her nothing about Jeff and Lynn, including their marriage. Kramer then addresses Jeff, offering to call an ambulance for Lynn if he accepts one final test: he can choose to kill Kramer or forgive him. Jeff tells Kramer he forgives him, but then slashes his throat with a power saw. The door to the sickroom seals itself as a dying Kramer plays a final tape, which tells Jeff that he has failed his test by killing Kramer, the only person who knows Corbett's whereabouts; to save her, Jeff must play another game. The tape ends as Kramer dies, and the collar promptly detonates and kills Lynn, leaving a screaming Jeff trapped in the sickroom with the three corpses., Question: What does Amanda put around Lynn's throat?
answer:
Answer: Collar
