In this sequel to Blueberry Hill, the boys of the Catholic metal working-class, who are now all working, decide to take revenge on the hated former principal Verbiest, after the sanctimonious `pillar of society` assaulted one of their girls. Since he is now a close collaborator of the Belgian minister of education, planning to launch his own political career by showing off a fund-raising telethon on Flemish TV, where one of the boys works as a technician, they decide to expose him on the air.
