[EX Q]: Context: Ryu (Ha-kyun Shin), a deaf man, works in a factory to support his ailing sister (Ji-Eun Lim) in desperate need of a kidney transplant. Ryu tries to donate one of his kidneys to his sister but is told that his blood type does not match that of his sister and so is not a suitable donor. After being laid off from his job by the factory boss, Ryu contacts a black market organ dealer who agrees to sell him a kidney suitable for his sister in exchange for 10,000,000 Korean won, plus one of Ryu's own kidneys. He takes the severance pay from his factory job and offers the money to the organ dealers, who take the money and one of his kidneys, but then disappear. Three weeks later, Ryu learns from his doctor that a kidney has been found for his sister and that the operation will cost 10,000,000 won, but since the organ dealers stole his money, he will not be able to pay for it.In need of money for the operation and in retaliation for his being fired, Ryu and his girlfriend, Yeong-mi (Doona Bae), a radical anarchist, conspire to kidnap the daughter of the boss who fired him. Instead, he realizes that the kidnapping would immediately put them under police suspicion, and they decide to kidnap Yu-sun (Bo-bae Han), the daughter of the boss's friend, Park Dong-jin (Kang-ho Song), another factory executive. The girl stays with Ryu's sister (thinking that Ryu is merely babysitting for a time), who takes care of her while the distraught Dong-jin arranges to pay her ransom. After Ryu collects the money and returns home, he learns that his sister has discovered his scheme and, unwilling to be involved or burden Ryu further, killed herself. Ryu takes Yu-sun and his sister's body into the countryside to bury her by a riverbed they used to frequent as children. While Ryu mourns, Yu-sun accidentally slips into the river and drowns.Days later, as Dong-jin mourns his daughter and swears revenge at the river bank, Ryu ambushes and murders the organ dealers. Dong-jin, having investigated the identities of the kidnappers, finds Yeong-mi and begins interrogating her. Yeong-mi apologizes for Yu-sun's death but warns him of her membership in a terrorist organization that, knowing Dong-jin's identity, will kill him if she dies. Dong-jin, unfazed by the threats, tortures her to death by electrocuting her. Ryu returns to Yeong-mi's apartment building and discovers the police removing her body on a stretcher. Ryu, consumed with grief, swears vengeance on Dong-jin.Ryu arrives at Dong-jin's residence in an attempt to kill him. He waits for some time, but Dong-Jin does not arrive: he is, in fact, waiting at Ryu's apartment. After Dong-Jin does not arrive, Ryu returns to his apartment. However, Dong-jin had previously set up an electric booby trap on his doorknob, which renders Ryu unconscious. Dong-jin then binds Ryu and returns him to the riverbed where Yu-sun died. After binding Ryu's hands and feet and bringing him chest-high into the water, an emotional Dong-jin acknowledges that although Ryu is a good man, he has no choice; Dong-jin then slashes Ryu's Achilles tendons, resulting in his drowning.Dong-jin drags Ryu back to shore and then drives off to a desolate location to bury the body. Once there, he begins to dig a hole, but soon a group of men arrives. They surround and stab Dong-jin repeatedly, finally attaching a note to his chest identifying themselves as the terrorist group of which Yeong-mi was part. The group leave Dong-jin dying beside his car with the bloody tools and bags he used to chop up, dismember, and package Ryu's body.(From Wikipedia.)

[EX Q]: Context: The film explores adolescent issues through the minds of three friends and their reactions after a boy named Rudy Carges (Conor Donovan) is killed in a tree house set on fire by local bullies Jeff and Kenny, who carelessly didn't find out he was inside until too late. The boy's twin brother Jacob, a boy with a huge birthmark (also played by Donovan), decides to seek revenge against the bullies. Leonard (Jesse Camacho) who's overweight, survives the tree house fire but loses his sense of taste and smell. Thanks to the fire, this prompts Leonard to go on a diet, which isn't welcomed by his obese family. The boys' female friend Malee (Zoe Weizenbaum) tries to befriend an adult named Gus (Jeremy Renner), a grief-stricken patient of her therapist mother, Carla (Annabella Sciorra). Jacob's family falls apart after the death of his brother. But shortly after, his parents adopt a boy named Keith Gardner. Meanwhile, Malee begins to have a crush on Gus and changes the song for her recital to one Gus liked, just for him. As time goes by, she sees Gus as her "soul mate". She sneaks into his house one night to find him grieving. Afraid to confront him, Malee steals his gun and leaves. She gives it to Jacob the following day. Jacob frequently visits Jeff and Kenny, who are serving time in a juvenile hall. Jacob initially threatens them, until eventually Jeff commits suicide. Jacob befriends Kenny, soon learning he has an early release and is illegally moving to New Mexico. Meanwhile, Leonard's father decides to take his sisters to Florida instead of Leonard (who would usually go). Leonard decides to force his mother to lose weight by trapping her in the cellar. They both end up in the hospital after a gas leak in their home. Next, Jacob and Kenny agree that Jacob can go with him to New Mexico. Malee visits Gus and removes her clothes in an attempt to seduce him. Instead, Gus calls Malee's mother to come and pick her up. The next day, Gus explains to therapist Carla about the last fire he ever fought (which involved killing an injured little girl, upon the girl's request), claiming that Malee wanted him to take her pain away, as he was aware of her growing crush on him. Meanwhile, Jacob's mother tells him that Keith Gardner wasn't adopted to replace Rudy, and that she wants Kenny dead, which reminds Jacob of his planned revenge. The night of escape for Jacob finally comes and he meets up with Kenny. Jacob insists on going through a construction site which he says is a secret route. Once there, Jacob points Gus's gun at Kenny, and tells him "you killed him" before shooting him dead. Jacob buries the body and leaves. He returns in the daytime, and sees Gus spreading cement above Kenny's grave. Malee begins visiting her estranged father and Leonard's family finally starts eating healthily. The movie ends with Jacob's mother smiling at him from inside the house.
