In an irresistible impulse to escape the bindings of modern society, a young man named Christopher McCandless decides to renounce his conventional life and embark on a journey into the unknown. After graduating from college, he donates all his savings to charity and says goodbye to his family, feeling that materialism and urban life have stolen his essence. With just a backpack and an unwavering ambition, he travels across the vast landscapes of the United States, from the warmth of California to the cold of Alaska, where he longs to experience nature in its purest form.
Throughout his journey, Chris, who adopts the name "Alexander Supertramp," encounters various people who leave a mark on his life: a hippie couple with immense hearts, a road friend seeking redemption, and a lonely old man who offers him wisdom about life. Each encounter teaches him valuable lessons about friendship, love, and the search for identity. However, the pursuit of his dream to live in the solitude of the wild becomes a journey filled with challenges and sacrifices.
In the end, Chris confronts the harsh reality of survival, where freedom and solitude come at a price. The internal struggle between the quest for truth and the desire for belonging will lead him to discover not only the wonders of the natural world but also the profound human connections that truly give life meaning.
