In September 2020, a trial opened at the Palais de Justice in Paris to judge those who participated in the murderous attempt to destroy a newspaper. This historic trial is that of those days in January 2015, when France witnessed live the assassination of the editorial staff of "Charlie Hebdo", the very person who had revived the newspaper in 1992. In 2020, it is in a bunker in Paris, that a new editorial staff still keeps freedom of expression alive. Starting with the trial of the January 2015 attacks and immersed in the current editorial staff of the newspaper, this documentary returns in archives, testimonies and drawings on the history of "Charlie Hebdo".
