 The film is presented in a nonlinear narrative, cutting back and forth between McCandless' time spent in the Alaskan wilderness and his two-year travels leading up to his journey to Alaska. The plot summary here is told in a more chronological order.
In May 1992, Christopher McCandless (Emile Hirsch) arrives in a remote area just north of the Denali National Park and Preserve in Alaska and sets up a campsite in an abandoned city bus, which he calls The Magic Bus. At first, McCandless is content with the isolation, the beauty of nature around him, and the thrill of living off the land. He hunts wild animals with a .22 caliber rifle, reads books, and keeps a diary of his thoughts as he prepares himself for a new life in the wild.
Two years earlier, in May 1990, McCandless graduates with high honors from Emory University in Atlanta, Georgia. Shortly afterwards, McCandless rejects his conventional life by destroying all of his credit cards and identification documents. He donates $24,000, nearly all of his savings, to Oxfam and sets out on a cross-country drive in his well-used, but reliable Datsun B210 to experience life in the wilderness. However, McCandless does not tell his parents, Walt (William Hurt) and Billie McCandless (Marcia Gay Harden), or his sister Carine (Jena Malone) what he is doing or where he is going, and refuses to keep in touch with them after his departure, causing his parents to become increasingly anxious and eventually desperate.
At Lake Mead, Arizona, McCandless' car is caught in a flash flood, causing him to abandon it and begin hitchhiking. He burns what remains of his cash and assumes a new name: "Alexander Supertramp." In Northern California, McCandless encounters a hippie couple named Jan Burres (Catherine Keener) and Rainey (Brian H. Dierker). Rainey tells McCandless about his failing relationship with Jan, which McCandless helps rekindle. In September, McCandless arrives in Carthage, South Dakota and works for a contract harvesting company owned by Wayne Westerberg (Vince Vaughn), but he is forced to leave after Westerberg is arrested for satellite piracy.
McCandless then travels on the Colorado River and, though told by park rangers that he may not kayak down the river without a license, ignores their warnings and paddles downriver until he eventually arrives in Mexico. There, his kayak is lost in a dust storm, and he crosses back into the United States on foot. Unable to hitch a ride, he starts traveling on freight trains to Los Angeles. Not long after arriving, however, he starts feeling "corrupted" by modern civilization and decides to leave. Later, McCandless is forced to resume hitchhiking, after he is beaten by the railroad police.
In December 1991, McCandless arrives at Slab City, in the Imperial Valley region of California, and encounters Jan and Rainey again. There, he also meets Tracy Tatro (Kristen Stewart), a teenage girl who shows interest in McCandless, but he rejects her because she is underage. After the holidays, McCandless decides to continue heading for Alaska, much to everyone's sadness. One month later, while camping near Salton City, California, McCandless encounters Ron Franz (Hal Holbrook), a retired man who recounts the story of the loss of his family in a car accident while he was serving in the United States Army. He now occupies his time in a workshop as an amateur leather worker. Franz teaches McCandless the craft of leatherwork, resulting in the making of a belt that details McCandless' travels. After spending two months with Franz, McCandless decides to leave for Alaska, despite this upsetting Franz, who has become quite close to McCandless. On a parting note, Franz gives McCandless his old camping and travel gear, along with the offer to adopt him as his grandchild, but McCandless simply tells him that they should discuss this after he returns from Alaska; then, he departs.
Four months later, at the abandoned bus, life for McCandless becomes harder, and he becomes less discerning. As his supplies begin to run out, he realizes that nature is also harsh and uncaring. In the pain of realization, McCandless concludes that true happiness can only be found when shared with others, and he seeks to return from the wild to his friends and family. However, he finds that the stream he had crossed during the winter has become wide, deep, and violent due to the snow thaw, and he is unable to cross. Saddened, he returns to the bus, now as a prisoner who is no longer in control of his fate and can only hope for help from the outside. In a desperate act, McCandless is forced to gather and eat roots and plants. He confuses similar plants and eats a poisonous one, falling sick as a result. Slowly dying, he continues to document his process of self-realization and accepts his fate, as he imagines his family for one last time. He writes a farewell to the world and crawls into his sleeping bag to die. Two weeks later, his body is found by moose hunters. Shortly afterwards, Carine returns her brother's ashes by airplane from Alaska back to Virginia, in her backpack.
What caused Christopher's death?

 Jeffrey Beaumont (Kyle MacLachlan) returns to his logging home town of Lumberton, North Carolina from Oak Lake College after his father suffers a near-fatal stroke. While walking home from the hospital, he cuts through a vacant lot and discovers a severed ear. Jeffrey takes the ear to police detective John Williams (George Dickerson) and becomes reacquainted with the detective's daughter, Sandy (Laura Dern). She tells him details about the ear case and a suspicious woman, Dorothy Vallens (Isabella Rossellini), who may be connected to the case. Increasingly curious, Jeffrey enters Dorothy's apartment by posing as an exterminator, and while Dorothy is distracted by a man dressed in a yellow suit at her door (whom Jeffrey later refers to as the Yellow Man), Jeffrey steals her spare key.
Jeffrey and Sandy attend Dorothy's nightclub act, in which she sings "Blue Velvet", and leave early so Jeffrey can sneak into her apartment to snoop. He hurriedly hides in a closet when she returns home. However, Dorothy, wielding a knife, discovers him and threatens to kill him. Believing his curiosity is merely sexual and aroused by his voyeurism, Dorothy makes Jeffrey undress at knifepoint and begins to fellate him before their encounter is interrupted by a knock at the door. Dorothy hides Jeffrey in the closet. From there he witnesses the visitor, Frank Booth (Dennis Hopper), inflict his bizarre sexual proclivities which include inhaling an unidentified gas (possibly amyl nitrite), dry humping, and sadomasochism upon Dorothy. Frank is an extremely foul-mouthed, violent sociopath whose orgasmic climax is a fit of both pleasure and rage. He continually refers to her as "Mommy" and to himself as both the "Daddy" and the "Baby", who "want to fuck." Frank has kidnapped Dorothy's husband and son to force her to perform sexual favors; to "Do it for van Gogh." When Frank leaves, a sad and desperate Dorothy tries to seduce Jeffrey again and demands that he hit her, but when he refuses, she tells him to leave. When Jeffrey moves to leave, she asks him to stay, though he leaves anyway.
Jeffrey relays his experience to Sandy, asking her why there are people like Frank. Sandy in turn tells him of a wonderful dream she had about robins that she interprets as a sign of hope for humanity. Jeffrey and Sandy find themselves attracted to each other, though Sandy has a boyfriend.
Jeffrey again visits Dorothy's apartment and she tells him that although she knows nothing about him, she has been yearning for him. Jeffrey attends another of Dorothy's performances at the club, where she sings the same song. At the club, Jeffrey spots Frank in the audience fondling a piece of blue velvet fabric he cut from Dorothy's robe. Jeffrey follows Frank and spends the next few days spying on him. Shortly afterwards, two men that Jeffrey calls the Well-Dressed Man and the Yellow Man exit an industrial building that Frank frequently visits. Jeffrey concludes the men are criminal associates of Frank, and tells his new findings to Sandy. The two briefly kiss, though she feels uncomfortable about going any further. Jeffrey immediately visits Dorothy again, and the two have sex. However, when he refuses to hit her, she pressures him, becoming more emotional. In a blind rage he knocks her backwards and is instantly horrified, but Dorothy derives pleasure from it.
Afterwards, Frank catches Dorothy and Jeffrey together and forces them both to accompany him to the apartment of Ben (Dean Stockwell), his suave, effeminate partner in crime who is holding Dorothy's son. Ben lip-syncs a performance of Roy Orbison's "In Dreams", sending Frank into maudlin sadness, then rage. Frank takes Jeffrey to a lumber yard and when he molests Dorothy, Jeffrey stands up to Frank by punching him. Frank's cronies drag Jeffrey out of the car and Frank kisses Jeffrey's face, intimidates him, and then savagely beats him to the overture of "In Dreams". Jeffrey wakes the next day at the same place and walks home, overcome with guilt and despair. He goes to the police station, where he notices that Sandy's father's partner is the Yellow Man an officer named Lieutenant Detective Tom Gordon (Fred Pickler). Later, at Sandy's home, her father is amazed by Jeffrey's story, but warns Jeffrey to stop his amateur sleuthing lest he endanger himself and the investigation. Jeffrey and Sandy go to a dance together and profess their love, only to be confronted by Sandy's boyfriend. A confrontation is averted when the group finds Dorothy naked, battered, and distressed on Jeffrey's front lawn. Barely conscious, Dorothy reveals her intimacy with Jeffrey, causing Sandy to become upset and to slap Jeffrey, although she later forgives him.
Jeffrey insists on returning to Dorothy's apartment and tells Sandy to immediately send the police there, including her father. At Dorothy's apartment, Jeffrey finds Dorothy's husband (Don Vallens), who is dead from a gunshot to the head and identifiable by his missing ear, as well as the Yellow Man (Gordon), who bears a gruesome head wound and appears to have suffered a crude lobotomy. When Jeffrey tries to leave, he sees the Well-Dressed Man coming up the stairs and recognizes him as Frank in disguise. Jeffrey talks to Detective Williams over the Yellow Man's police radio, but lies about his location inside the apartment. Frank enters the apartment and brags about hearing Jeffrey's location over his own police radio. While Frank searches for him in the wrong room, Jeffrey retrieves the Yellow Man's gun and hides in the same closet in which he hid during his first visit to the apartment. Frank fires sporadically, knocking over the dead Yellow Man, who had still been standing up, and when he opens the closet door, Jeffrey fatally shoots him in the head. Detective Williams, gun drawn, enters with Sandy a moment later. Jeffrey and Sandy now go ahead with their relationship and note the unusual appearance of robins in their town. A montage sequence ends the film, which shows Dorothy and her son reunited.
Who plays the role of Dorothy Valens?

 The beginning of the movie shows icemen harvesting ice. A young boy named Kristoff and his pet reindeer, Sven, is among them ("Frozen Heart"). Elsa, Princess of Arendelle, possesses cryokinetic powers, with which she is able to produce or manipulate ice, frost and snow at will. One night while playing, she accidentally injures her younger sister, Anna. Their shocked parents, the king and queen, seek help from the troll king, who heals Anna and removes her memories of Elsa's magic. The royal couple isolate the sisters in the castle until Elsa learns to control her magical powers. Afraid of hurting Anna again, and with her ability to control her powers deteriorating, Elsa spends most of her time alone in her room, refusing even to speak to Anna and a rift develops between the sisters as they grow up; when the girls are teenagers, their parents die at sea during a storm ("Do You Want to Build a Snowman?").
When Elsa comes of age, the kingdom prepares for her coronation ("For the First Time in Forever"). Among the guests is the Duke of Weselton, who seeks to exploit Arendelle for profit. Excited to be allowed out of the castle again, Princess Anna explores the town and meets Prince Hans of the Southern Isles; the two quickly develop a mutual attraction. Despite Elsa's fears, her coronation takes place without incident. During the reception, Hans proposes to Anna, who hastily accepts ("Love Is An Open Door"). However, Elsa refuses to grant her blessing and forbids their sudden marriage. The sisters argue, culminating in the exposure of Elsa's abilities in an emotional outburst.
Declared a monster by the Duke, a panicking Elsa flees the castle, while inadvertently unleashing an eternal winter on the kingdom. High in the nearby mountains, she abandons her restraint, vowing to never return and building herself a solitary ice palace ("Let It Go"). Meanwhile, Anna leaves Hans in charge of Arendelle and sets out in search of her sister, determined to return her to Arendelle, end the winter and mend their relationship. While obtaining supplies from 'Wandering Oaken's Trading Post and Sauna', Anna meets Kristoff and Sven ("Reindeers Are Better Than People"). She convinces Kristoff to guide her up the North Mountain. On their journey, the group encounters Olaf, Anna and Elsa's childhood snowman whom the latter recreated and unknowingly brought to life. Olaf dreams of seeing and experiencing summer for the first time ("In Summer"). He then leads them to Elsa's hideaway.
Anna and Elsa reunite, but Elsa still fears hurting her sister. When Anna insists that Elsa return, she becomes agitated and her powers lash out, accidentally striking Anna in the heart ("For the First Time In Forever (Reprise)"). Horrified, Elsa forces Anna, Kristoff and Olaf to leave by creating a giant snow creature named Marshmallow that chases them away from her palace. As they flee, Kristoff becomes concerned when he sees Anna's hair turning white. He seeks help from the trolls, his adoptive family, who explain that Anna's heart has been frozen by Elsa ("Fixer Upper"), and that unless it can be thawed by an "act of true love", she will become frozen solid forever. Believing that only Hans can save her with a true love's kiss, Kristoff races back with her to Arendelle.
Hans, who is himself leading a search for Anna, reaches Elsa's palace. In the ensuing battle against the duke's men, Elsa is knocked unconscious by a falling chandelier and imprisoned in Arendelle. There, Hans pleads with her to undo the winter, but Elsa confesses that she has no idea how. When Anna reunites with Hans and begs him to kiss her to break the curse, Hans refuses and reveals that his true intention in marrying her is to seize control of Arendelle's throne. Leaving Anna to die, he charges Elsa with treason for her younger sister's apparent death.
Elsa escapes and heads out into the blizzard on the fjord. Olaf comes across Anna and reveals Kristoff is in love with her; they then escape onto the fjord to find him. Hans confronts Elsa, telling her Anna is dead because of her. In Elsa's despair, the storm suddenly ceases, giving Kristoff and Anna the chance to locate each other. Nevertheless, Anna, seeing that Hans is about to kill Elsa, throws herself between the two just as she freezes solid, blocking Hans' attack.
As Elsa grieves for her sister, Anna begins to thaw, since her decision to sacrifice herself to save her sister constitutes an "act of true love". Realizing love is the key to controlling her powers, Elsa thaws the kingdom and gives Olaf his own personal flurry so he can survive in summer. Hans is deported to the Southern Isles to face punishment for his crimes against the royal family of Arendelle, while Elsa cuts off trade with Weselton. The two sisters reconcile and Elsa promises never to shut the castle gates again.
