A cartoonist sits down at his drawing table. In front of him lies a blank page. In seven days, the blank page will have become a comic book. Loneliness, hardship, mastery, brilliance, deadlock, discouragement... What mysterious paths will the cartoonist take? A film that delves into the intimacy of the studio of Jean-Claude Mézières, one of the masters of the Ninth Art. A comic lesson in real time, day after day.
