A forge furnace has exceeded 3,000 degrees and a scrap collector insists on opening it to retrieve material despite Master Lever and workers saying the scrap vaporized and tools can't handle the heat. He refuses—"I have my ways"—and works without gloves, so the crowd calls him insane. Sir warns opening it rashly will blast and burn everyone. Marilyn rushes forward, shouting, "Let me go! I'll save him!" but is held back as others warn she'll die. The furnace stays out of control, leaving the attempted rescue and both lives in immediate danger.
