It is August 1959. In a social housing unit in Bobigny, on the outskirts of Paris, two comic book writers are wiping their sweat. Not only because of the summer heat: the two friends are making every effort to come up with a character idea. They must be ready for the first issue of Pilote, a new magazine for young people that will be published three months later. The screenwriter is named René Goscinny. His friend, the illustrator, is Albert Uderzo. They had considered adapting "The Romance of Renard," but someone else thought of it before them. So, they search. But they find nothing... Until Goscinny has the idea of a small, wild-looking Gallic with a mustache. Bingo: Asterix is ready. Along with him comes a spectacular edition that doubles a social phenomenon.
