Plot
Louis Drax, a 9-year-old boy, narrates a series of near-fatal accidents, the most recent being a suspicious fall off a cliff. Through a series of flashbacks, Louis's sessions with psychiatrist Dr. Perez are shown. Additional flashbacks reveal a strained relationship between Louis's parents, Peter and Natalie. Despite Dr. Perez promising that everything Louis told him would be confidential, he tells Natalie about his concerns, causing her to end the sessions.
In the present, a doctor examining Louis after his latest accident pronounces him dead. After Louis is transported to the morgue, however, he suddenly awakes, and is placed in intensive care in a coma. Peter, who has disappeared, is immediately the primary suspect in the possible attempted murder of Louis. Louis's case attracts the attention of Dr. Allan Pascal, who becomes the lead doctor in charge of Louis's care. Despite Allan being married, he and Natalie share a mutual attraction, and he kisses her one day while the two go on a walk.
Natalie and Allan receive threatening letters telling them to stay away from each other, with the author of said letters claiming to be Louis himself. Dalton, the lead investigator on Louis's case, believes the letters to be written by Peter. Dalton warns Allan not to become involved with Natalie, telling him that Peter is not Louis's real father, and at one point Natalie attempted to give Louis up for adoption. Natalie confesses to Allan that Louis was the result of rape, and despite Dalton's warnings, she and Allan have sex.
Louis is visited in the hospital by his grandmother, Violet, who notices Allan and Natalie's relationship. She warns Allan that Natalie is unstable and manipulative. Dalton suddenly enters, informing Violet and Allan that Peter's body has been found at the bottom of a cliff, having been dead for several days.
While all of the above is happening, Louis continues to narrate. At certain points he is visited by a mysterious creature covered in seaweed. Louis visits the creature in a cave, and it is revealed to be Louis's manifestation of Peter, who was found dead in a cave covered in seaweed.
One day, while waking up from a nap, Allan is told by another doctor that not only did he sleepwalk during his nap, but he also wrote a prescription for Natalie, for dangerous doses of insulin and chloroform. This, combined with Allan's other dreams and the suspicious letters, leads Allan to believe that while he sleeps, Louis has somehow been controlling him and his actions. Allan informs Dr. Perez, who hooks Allan up to an EEG and manages to directly communicate with Louis via Allan's mind and voice.
Louis reveals what happened during the picnic: Natalie tries to give Louis some candy but refuses to allow Peter to have any, making Peter suspicious and leading to a fight. Louis flees to the cliff edge, while Natalie and Peter follow and get into a scuffle, which ends when Natalie pushes Peter off the cliff to his death. Louis sees this and walks off the edge of the cliff on his own in an apparent suicide attempt.
At this point, Louis's heartbeat suddenly stops and Allan wakes up. While Allan tries to revive him with a defibrillator, it is shown that Natalie is responsible for Louis's "accidents," having done things such as poison his candy, electrocute him while near a socket, and smother him with a pillow. Allan succeeds in restarting Louis's heart while Natalie looks on.
Some time later, Allan moves out after separating from his wife. He visits Natalie, who has been placed in a psychiatric ward under Dr. Perez's care. Perez explains to Allan that he has diagnosed Natalie with Munchausen syndrome by proxy. It is shown that Natalie is now pregnant, presumably with Allan's child.
In a final narration, Louis ponders whether being in a coma forever is bad, as it allows him to stay with his father. Peter's voice, however, tells Louis that the world is beautiful and he needs to grow up and live his life. Louis awakens from his coma, and the film ends.
