In 1952 two young Argentines — medical student Ernesto Guevara and his friend Alberto Granado — set out to cross South America by motorbike. What starts as a youthful adventure becomes something else entirely as they meet dispossessed miners, exploited workers and communities the world had forgotten. Walter Salles's award-winning film traces the journey that turned a shy student into the revolutionary the world would come to know as Che.
