A biking accident lands Lopez in a hospital.One day, he hears a violin being played beautifully. Investigating, he encounters Nathaniel Ayers (Jamie Foxx), a homeless man with schizophrenia, who is playing a violin when Lopez introduces himself. During the conversation that follows, Lopez learns that Ayers once attended Juilliard.Curious as to how a former student of such a prestigious school ended up on the streets, Lopez contacts Juilliard but learns that no record of Ayers graduating from it exists. Though at first figuring a man with schizophrenia who's talented with a violin isn't worth his time, Lopez soon realizes that he has no better story to write about. Luckily, he soon learns that Ayers did attend Juilliard, but dropped out after two years.Finding Ayers the next day, Lopez says he wants to write about him. Ayers doesn't appear to be paying attention. Getting nowhere, Lopez finds and contacts Ayers' sister (Lisa Gay Hamilton), who gives the columnist the information he needs: Ayers was once a child prodigy with the cello, until he began displaying symptoms of schizophrenia at Juilliard. Unable to handle the voices, Ayers dropped out and ended up on the streets due to the delusion that his sister wanted to kill him. Without a cello, he has resorted to playing a two-string violin.Lopez writes his article. One reader is so touched, she sends him a cello for Ayers. Lopez brings it to him and Ayers is shown to be just as proficient as with a violin. Unfortunately, his tendency to wander puts both Ayers and the cello in danger, so Lopez talks him into leaving it at a shelter, located in a neighborhood of homeless people. Ayers is later seen playing for the homeless.A concerned Lopez tries to get a doctor he knows (Nelsan Ellis) to help. He also tries to talk Ayers into getting an apartment, but Ayers refuses. After seeing a reaction to music played at an opera house, Lopez persuades another friend, Graham (Tom Hollander), a cellist, to rehabilitate Ayers through music. The lessons go well, though Ayers is shown to be getting a little too attached to Lopez, much to the latter's annoyance. Lopez eventually talks Ayers into moving into an apartment by threatening to abandon him.Lopez's article on Ayers gains so much fame, Ayers is given the chance to perform a recital. Sadly, he loses his temper, attacks Graham and leaves. This convinces Lopez's doctor friend to get Ayers help. But when Ayers learns what Lopez is up to, he throws Lopez out of his apartment and threatens to kill him.While speaking with Mary, Lopez realizes that not only has he changed Ayers' life, Ayers has changed him. Determined to make amends, Lopez brings Ayers' sister to L.A. for a visit. Ayers and Lopez make up. Later, while all watch an orchestra, Lopez ponders how beneficial their friendship has been. Ayers still hears voices, but at least he no longer lives on the streets.

A suicidal man, just before jumping into the river, sees something dark moving in the water.In 2006, a slow-witted young man named Park Gang-du (Song Kang-ho) runs a small snack-bar in a park near the River with his father, Hee-bong (Byun Hee-bong). Other family members are Gang-du's daughter, Hyun-seo (Go Ah-sung); his sister Nam-joo (Bae Doona), a national medalist archer; and his brother, Nam-il (Park Hae-il), an alcoholic college graduate and former political activist.While Gang-du is delivering food to some customers, a huge creature emerges from the Han River and begins attacking people. Gang-du sees his daughter in the crowd and tries to grab her and run. As he realizes he grabbed on the wrong girl, he sees the creature snatching Hyun-seo and diving back into the river. After a mass funeral for the victims, government representatives and the American military arrive and quarantine people who had contact with the creature, including Gang-du and his family. It is announced that the creature is not only a direct danger, but also the host of a deadly, unknown virus.Gang-du is in a hospital when he receives a phone call from Hyun-seo. She is trapped somewhere in the sewers with the creature. Gang-du tries to explain this to others, but his claims go ignored by all except his family. The four of them escape the hospital. Hee-bong buys a truck, weapons, and a map of the sewers to look for Hyun-seo. They find a snack bar, have a meal and rest. Upon waking up, they encounter the creature. Soon, they discover their gun only serves to anger it, and Hee-bong gets himself killed buying time for his children to escape. Gang-du is captured by the Army. Nam-il and Nam-joo escape but are separated from each other.Two homeless boys, Se-jin and Se-joo, are searching for food when they are attacked and swallowed by the creature.

The scientists lobotomize Gang-du to silence him. As he wakes up, he hears the scientists discussing the fact that there is no virus; it is all made up to distract people from the creature's origin. Gang-du escapes by taking one of the nurses hostage and continues searching for his daughter.Back in the sewers, while the creature is sleeping, Hyun-seo makes a rope from old clothes and uses it to get out of the hole. She realizes too late that the creature only feigns sleep to lure her out of her hiding spot.

The creature makes its way to the location where Agent Yellow is released and a large crowd has formed in protest.As the creature attacks the crowd, Agent Yellow is released, which appears to stun the creature. Gang-du pulls Hyun-seo out of its mouth and sees her still clutching Se-joo. The boy is still alive, but Hyun-seo is already dead.As the creature wakes up, Gang-du starts to attack it but is knocked to the ground. Nam-il and the homeless man come to Gang-du's aid. While Nam-il throws Molotov cocktails at the creature, the homeless man pours gasoline onto it. Nam-il accidentally drops his last bottle. Nam-joo picks up the flaming cloth from the bottle with one of her arrows and fires it at the creature, setting it on fire. Before the creature can escape into the water, Gang-du impales it with a metal pole, finally killing it. As Nam-il and Nam-joo hold Hyun-seo, mourning her death, Gang-du picks up Se-joo and takes him to safety.In the final scene, Gang-du has adopted Se-joo.
