Lulu Massa is a highly productive worker at a factory paying piece work but is disliked by his colleagues as his efficiency is used by management to justify their demands for higher output. While employees are told to care for and rely on their machines, they see radical students outside the factory campaigning for higher pay rates and less work. Lulu lives with Lidia and her son. He puts his lack of interest in sex with her down to the pressures of the job.
