本片讲述了，在30年代的美国，一个谋杀儿童的连环杀手Albert Fish的故事。 A solid thriller about Albert Fish (a very fine performance by Patrick Bauchau), the real life serial killer of children in 1930's America. Fish seemed a harmless old man, but in 1934 he was arrested as the murderer of several missing children he somehow duped their families into leaving him with (using an assumed name throughout). Part character study and part detective procedural, The Gray Man wisely avoids graphic horror and sensationalism (Fish's murders, for instance, are never shown on camera), and while it is rather conventional, it is nevertheless quite chilling nonetheless and it shows a director with a very keen sense of storytelling.
