A strike has broken out in a big factory in the North of France. Two workers, Robert and Etienne, go through the experience in a different way. Etienne, who has worked there since the start, is still influenced by the time when workmen and their bosses found an agreement directly. Unlike him, his young friend believes in the power of labor unions. He even goes to Paris to attend special classes in trade unionism.
