This episode shows an American, formerly considering herself the leader of the free world, in a hedonistic death spiral. Meanwhile, a South American pursues his dream to save the world, encouraged by the history of said American, by taking the absolute hardest path. The South American takes it upon himself to learn another language while undertaking his perilous journey, ready to assimilate to the culture.
