A hard-working machinist loses a promotion to a Polish-born worker, he's seduced into joining the secretive Black Legion, which intimidates foreigners through violence.
Frank Taylor joins the "pro-American" Black Legion when he loses his chance at foremanship to a foreign-born man. The organization is a sort of Ku Klux Klan in the industrial sphere. Frank has troubles with his wife over this and causes serious trouble when he tells all to his best friend Ed Jackson.
