Che Guevara's face sells more t-shirts than perhaps any other twentieth-century figure, but this film tracks the man underneath the print: an Argentine doctor who crosses South America by motorcycle, joins Fidel Castro's guerrilla campaign in the Sierra Maestra, and helps topple Fulgencio Batista in 1959. It follows him into Havana's La Cabaña fortress, where as commander he oversees the trials and executions of men labeled enemies of the revolution, and into the ministries where he tries to build a socialist economy by decree. Interviews and archival footage weigh his writings on anti-imperialism and self-sacrifice against the reality of a prison system built to silence dissent. The film also turns to the commercial afterlife of his image, tracing how a guerrilla fighter became a marketing logo stripped of the politics he died for. Rather than settling on hero or villain, it lays out the contradictions side by side: physician and executioner, revolutionary theorist and enforcer of a one-party state, and leaves the verdict to the viewer.
