麦克纳马拉（詹姆斯·贾克内 James Cagney 饰）是可口可乐公司西德分部的总经理，长久以来，他默默地为公司辛勤工作，业绩屡创新高，是上司眼中的红人，亦是最有希望获得晋升的职员。某日，上司致电麦克纳马拉，告知他自己的女儿斯嘉丽（帕梅拉·蒂芬 Pamela Tiffin 饰）即将前往西德游玩，希望麦克纳马拉能够成为她的监护人。
然而，让麦克纳马拉没有想到的是，斯嘉丽尽管年纪轻轻，个性却极其热情奔放，来西德没多久，便同一位名叫奥托（豪斯特·巴奇霍兹 Horst Buchholz 饰）的男子坠入了爱河，他们不仅结了婚，斯嘉丽的腹中甚至还有了奥托的骨肉，更糟糕的是，奥托来自于东德，是一位根正苗红的社会主义者，鄙视资本主义的一切。就在这个节骨眼上，麦克纳马拉得知上司很快就要前往西德接他的女儿。

Director Wolfgang Staudte who left East Germany in 1953 to make movies in West Germany, takes a few swipes at the West German judicial system in this fairly effective courtroom drama about the murder of a four-month-old baby. Police almost immediately arrest the mother Ingrid who is the mistress of the father, a rich business VIP married to another woman. His position and wealth keep him insulated from suspicion. A hot-shot lawyer has to overcome the unaccountably biased perceptions of the police, the judge, the prosecutor and almost everyone else in the judicial system. The defence lawyer, driven to an extreme, knows he has to find the real killer or his client will be convicted.
