François Cavanna was one of the two founders of “Charlie Hebdo” and “Hara Kiri” – the French satirical magazines that galvanized not only the French society sustainably. He passed away aged 91, just one year prior to the deadly attack of January 2015. With amazing and often hilarious archives, this documentary takes us through the history of his work and what freedom of speech really means. This is the story of the first man who could say “I am Charlie”.
