In 1960, Cuban photographer Alberto "Korda" Díaz captured a photo of Ernesto "Che" Guevara during a mass funeral. History conspired to enable this dynamic portrait to explode on the world scene in 1968 throughout Europe and Latin America, when it became an international symbol of protest and dissent. In the last decade, with the establishment of the internet, the image has once again travelled the globe in many forms. From protest to commerce, it is constantly transformed and reinvented. It is considered to be the most reproduced image in the history of photography. Why and how did this photograph become so important? Chevolution is a film about a photograph. It explores how the Che image travelled from Korda's studio in Havana to the streets of Europe and beyond. We investigate how this portrait with its enigmatic gaze became a symbol for countless visions for change.
