若者の旗 (1970)

The final part of the trilogy. It is about a younger brother, Suekichi. He learned well the lessons that life taught his older brothers. Therefore, he does not think to study, but strives for material well-being alone. To make a career, he ruthlessly pushes his colleagues with his elbows. For him, the high ideals of trade union activists Jiro and Saburo are an example of old-fashioned thinking, naive behavior.
