记述了在战时伦敦空袭中一个灭火队的一个夜晚，“是孤立的和被包围的不列颠的一幅令人惊奇而又倍感亲切的肖像”。消防员们冒着生命危险彻夜奋战，影片避免了强烈的爱国主义，更热衷于讽刺的、诗意的凝视。A new man joins the civilian firefighters at a London unit during the Second World War. He meets his fellow firemen and firewomen, manages to enjoy some leisure time with them, and then goes on his first mission with the crew as it attempts to save an explosives warehouse on Trinidad Street near the London docks.
