The film recounts the 1952 expedition, initially by motorcycle, across South America by Guevara and his friend Alberto Granado.  As well as being a road movie, the film is a coming-of-age film; as the adventure, initially centered on youthful hedonism, unfolds, Guevara discovers himself transformed by his observations on the life of the impoverished indigenous peasantry.  Through the characters they encounter on their continental trek, Guevara and Granado witness firsthand the injustices that the destitute face and are exposed to people and social classes they would have never encountered otherwise.  To their surprise, the road presents to them both a genuine and captivating picture of Latin American identity.  As a result, the trip also plants the initial seed of cognitive dissonance and radicalization within Guevara, who ostensibly would later view armed revolution as a way to challenge the continent's endemic economic inequalities and political repression.
