After dedicating himself to the workers' cause, he tells them that he will appeal to the bosses to become a check weigh man who measures the amount of coal, but the GFC, wanting to cheat the workers out of their pay, appoints a company check weigh man.
The workers organize a strike and union to demand their rights from the bosses, but the rescue effort goes longer than expected.
