本片以第二次世界大战末期，在意大利登陆的美军攻破德军防线为背景，导演以令人感动的场面把美军从南部攻到北部期间所引发的一些意大利民间故事编成一部有连贯性的社会写实的电影，画面上的真实感，给予人们非常大的冲击，创下了意大利电影的新潮流…… 大师罗西里尼的战后三部曲的第二部，第一部是《罗马，不设防的城市》，最后一部是《德意志零年》。作为新现实主义的奠基人，罗西里尼几乎不使用剧本，并明确拒绝使用摄影棚、服装、化妆和职业演员。影片由6个小故事组成，背景是二战后期盟军在意大利登陆后攻破德军防线，从南部向北部进攻期间引发的一些民间小故事。罗西里尼在摄影机前重现了美国大兵，游击队员、修道士等，以及普通平民在那个烽火连天的岁月里的真实遭遇，影片穿插了很多真实的战争镜头，令观众感同身受。
