罗马尼禄皇帝在位时，指挥官维尼吉将宫大胜而回，对利吉国在罗马的人质丽吉儿公主一见钟情，尼禄遂将丽吉儿赏给维将军，未料丽吉却是基督徒，与维将军主张以征服和屠杀一统天下的理念，在心灵上无法沟通，遂逃离。

　　为追回丽吉儿，维将军寻至基督徒秘密集会处，初闻彼得关于基督的说教，回程再见到丽吉儿时，虽然此时两人已相爱，但对基督的精神仍感迷感。在回皇宫时碰上疯狂的尼禄为建尼禄之城而焚烧罗马城，维将军赶回火场，救出丽吉儿，并率领民众突围，难民涌入皇宫，皇后城护维将军对丽吉儿的爱，怂勇禄将焚城之罪嫁祸基督徒，将捕获的基督徒或喂猛狮或钉十字架或烈火焚烧。圣彼得亦被子钉十字架而亡，但所有的基督徒均高唱圣歌就义，维将军当场揭发真相，罗马大军反正，尼禄自杀结束暴行。
