How does a politician – assassinated some thirty-five years ago – gradually become a public figure? An extremely vibrant image which shows up where you least expect it. It recently served as figurehead for the Arab Spring revolutions, from Rabat to Sanaa, whereas we had thought it had been relegated to t-shirts and cigarette lighters. Why has this image become so universal that we are no longer surprised to find it in drawings, graffiti, tattoos and prints on all types of media in all sorts of contexts the world over? How can this image be used to advertise luxury automobiles and also be brandished angrily by indignant agitators? What is the formula that made this figure go viral? This documentary is a journey to investigate and decode a piece of iconography.
