影片中的男女主人公加利·格兰特与英格丽·褒曼的相遇完全是命运的安排。身为秘密情报部门特工的褒曼与同是联邦特工的格兰特在南美相遇，两人逐渐相爱。但出于任务需要，褒曼饰演的艾莉西娅由于上级的派遣与一位纳纯粹余党结婚，格兰特饰演的戴夫林却为了完成任务，眼睁睁地看着自己心爱的人在痛苦中煎熬着。艾莉西娅的身份暴露后，被现任丈夫以及家人暗地里用慢性毒药逐渐地地侵蚀着她年轻的生命，最后她在自己心爱的人的怀抱中，终于被进了医院。 影片以爱情与家国的矛盾冲突为线索，以悬念惊险为形式，两大特色并驾齐驱相得益彰，堪称最能体现希区柯克风格的佳作之一。而舞会酒窖一段、结尾救出莉亚一段，则是二者结合最为完美的经典段落。
