雷达(简·德克莱尔 Jan Decleir 饰)是一名冷酷而又残暴的杀手,身上背负着累累的血债。造化弄人,雷达换上了阿兹海默症,这也就意味着,随着时间的推移,他离“退休”越来越近了。在一次重要的任务中,雷达震惊的发现自己要暗杀的对象竟然是一个只有十二岁的孩子,悲惨的童年经历让他迟迟无法下手,并决定展开他的复仇计划。 雷达杀死了同僚吉尔斯(帕特里克·德康 Patrick Descamps 饰),制造了自己已死的假象。与此同时,出色的探员温科(肯·德·布沃 Koen De Bouw 饰)和韦斯特(沃纳·德·斯曼特 Werner De Smedt 饰)亦紧紧的追随在雷达的身后,想要将其绳之于法。Vincke and Verstuyft are one of the best detective teams of the Antwerp police force. When they are confronted with the disappearance of a top official and the murder of two prostitutes, the trail leads to the almost retired assassin Angelo Ledda. Since Ledda starts showing symptoms of Alzheimer's, it's getting more and more difficult to complete his contracts. When he has to murder a 12-year old call-girl, he refuses and becomes a target himself. While Vincke and Verstuyft are chasing him and counting the corpses, Ledda is taking care of his employers.
