他（伊万·麦格雷戈 Ewan Gordon McGregor 饰）是一个影子写手，一如其代号“Ghost（鬼魂）”一般，他深深躲在幕后，为各行各业的名流捉刀撰写回忆录。一日，鬼魂接到一项新的任务，即帮助前英国首相亚当·朗（皮尔斯·布鲁斯南 Pierce Brosnan 饰）的回忆录作润饰工作。此前，该书由亚当·朗在任期间的助手迈克·麦卡拉负责，然而麦卡拉却神秘自杀。看在丰厚报酬的份上，鬼魂接受了这项工作。在写书过程中，亚当受到战争罪的指控，政治风暴近在咫尺。而鬼魂也开始有意探知亚当不为人知的过去以及麦卡拉死亡的原因，却不知此举将他引入险途…… 　　本片改编自罗伯特·哈里斯（Robert Harris）的小说《枪手》，并荣获2010年柏林国际电影节银熊奖最佳导演奖。An unremarkable ghost-writer has landed a lucrative contract to redact the memoirs of Adam Lang, the former UK Prime Minister. After dominating British politics for years, Lang has retired with his wife to the USA. He lives on an island, in luxurious, isolated premises complete with a security detail and a secretarial staff. Soon, Adam Lang gets embroiled in a major scandal with international ramifications that reveals how far he was ready to go in order to nurture UK's "special relationship" with the USA. But before this controversy has started, before even he has closed the deal with the publisher, the ghost-writer gets unmistakable signs that the turgid draft he is tasked to put into shape inexplicably constitutes highly sensitive material.
