本片描述一名纳粹军官战后藏于南美洲,他野心勃勃地希望以科学方法进行人种试验,以便东山再起,使纳粹党重振雄风。但有一名犹太人以缉捕纳粹余孽为其终生职志,于是双方展开了一场惊心动魄的斗智斗勇。 本片快节奏且令人毛骨悚然,是一部颇有格调的间谍悬疑片,气氛处理甚佳。演员阵容强大,格里高利·派克和劳伦斯·奥利弗的表演内敛而有张力,可谓火候老到。Barry Kohler, a young Nazi hunter, tracks down a group of former SS officers meeting in Paraguay in the late 1970s. The Nazis, led by Dr Mengele, are planning something. Old Nazi hunter, Ezra Lieberman, is at first uninterested in Kohler's findings. But when he is told something of their plan, he is eager to find out more. Lieberman visits several homes in Europe and the U.S. in order to uncover the Nazi plot. It is at one of these houses he notices something strange, which turns out to be a horrible discovery.
