Britain’s most notorious serial killer, Dennis Nilsen, confessed to killing 15 people in 1983. Over a five-year period, he picked up vulnerable young men, lured them back to his home and strangled them, before disposing of their bodies under the floorboards The truth about how and why he killed has been the subject of much speculation in books and documentaries over the decades since. Now, with unique access to a wealth of personal archive left in his cell after his death, including over 250 hours of never-before-published cassette tapes of his private recordings, this film will take us into Nilsen’s world. From a young boy growing up in a quiet Scottish fishing village to a cold-blooded murderer prowling the streets of London. Set against the backdrop of 1980s Britain, when mass unemployment drew young men to London in search of their fortunes, only to find themselves destitute and easy prey, and weaving together interviews from police, journalists, survivors, bereaved families, and - for the first time - the killer’s own voice, this feature length documentary explores how Nilsen was able to get away with multiple murders and attacks, unchallenged, for five years.
作为一部纪录片，导演的观点却非常明确，而且喧宾夺主。当尼尔森说他是因为童年被祖父猥亵之后，导演借着记者之口说这没准只是他为了自己的行为找一个恶棍（替罪羊）。当他说英国社会当时对同性恋非常苛刻而导致自己对他人痛下杀手时，导演又跳出来说这是他（尼尔森）想让你相信的，是他的一面之词。这不是废话吗，这纪录片就是关于他的，他说的一切全部都是主观的，难道有任何一句会是“客观描述”吗？
感觉这个片的主题非常混乱，又想推出一个杀人狂又不想让这个杀人狂占据主导，永远需要推出各种相关人物来给上一两句建议或者论断，好像这个社会有问题但是却又不完全是社会的问题，堕落的年轻人落到这步田地完全是咎由自取。
最后还是那个苏格兰警察说得对，警察之所以能抓住凶手完全就是因为他碍着别人了，他造成的社会影响发生在他被捕之后而不是之前，这一点也算得上是一种绝佳的讽刺了。
