At first, McCandless is content with the isolation, the beauty of nature, and the thrill of living off the land. He hunts wild animals with a .22-caliber rifle, reads books, and keeps a diary as he prepares for himself a new life in the wild.Two years earlier in May 1990, McCandless graduated with high honors from Emory University. Shortly afterwards, McCandless rejects his conventional life by destroying all of his credit cards and identification documents. He donates nearly his entire savings of $24,000 to Oxfam, and sets out on a cross-country drive in his well-used yet reliable Datsun 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, leaving them to become increasingly anxious and eventually desperate.At Lake Mead, McCandless' automobile is caught in a flash flood. forcing him to abandon it and begin hitchhiking. He burns what remains of his dwindling cash supply 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 would rekindle. By September, McCandless stops in Carthage, South Dakota to work 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 to the Colorado River and, though he is told by park rangers that he may not kayak down it without a license, he 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 get a ride, he starts traveling via freight train to Los Angeles. Not long after arriving, however, he starts feeling corrupted by modern civilization and decides to leave. Later, McCandless is forced to switch his traveling method back to hitchhiking after he is beaten by a railroad bull.In December 1991, McCandless arrives at Slab City in the Imperial Valley of California, and encounters Jan and Rainey again. There he meets Tracy Tatro (Kristen Stewart), a teenager who falls for McCandless. After the holidays, McCandless decides to continue heading for Alaska, much to everyone's sadness. While camping near Salton City, California, McCandless encounters Ron Franz (Hal Holbrook), a retiree who recounts the story of the loss of his family in a car accident while he was serving in the 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 several months with Franz, McCandless decides to leave for Alaska despite the upset of Franz, who has become quite close to McCandless. On parting, 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 it after he returns from Alaska, and then departs.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 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 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, but he confuses similar plants and becomes ill 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 to Virginia in her backpack.
