Bruno, Pierre, Annick and Valentin are truck drivers. They are part of the thousands of men and women who criss-cross the roads of France and Europe day and night, driving their 44-ton trucks. Faced with the rapid growth of e-commerce, over the last 30 years, heavy goods vehicle traffic has increased by 50%. The world has never been so dependent on truckers. In the midst of a health crisis, they are one of those forgotten professions that have stepped up to the front line to keep society running. Who are they? What do we know about them? This film aims to give them a voice.
