During their expedition, Guevara and Granado encounter the poverty of the indigenous peasants, and the movie assumes a greater seriousness once the men gain a better sense of the disparity between the "haves" (to which they belong) and the obviously exploited "have-nots" (who make up the majority of those they encounter) by travelling on foot. In Chile, for instance, they encounter a penniless and persecuted couple forced onto the road because of their communist beliefs. In a fire-lit scene, Guevara and Granado ashamedly admit to the couple that they are not out looking for work as well. The duo then accompanies the couple to the Chuquicamata copper mine, where Guevara becomes angry at the treatment of the workers.
