经历了开膛手杰克的模仿者一案,Jones(鲁伯特·彭利·琼斯 Rupert Penry-Jones 饰)获得了所有所有下属的尊重,尤其是之前总是小看他的警探Miles(菲尔·戴维斯 Philip Davis 饰)。这一次他们要面对的凶手变得更加残忍、血腥。白教堂区陆续出现残忍谋杀案,凶手模仿的是上世纪50、60年代的著名黑帮孪生首脑Kray兄弟。经过进一步的调查,犯罪嫌疑人锁定在Kray兄弟的后代——Jimmy和Johnny这一对双胞胎身上。而他们这一次犯罪的目的就是向当年指证Kray兄弟的证人们报复,并巩固自己的黑帮势力。 这一次,他们是否能够成功将凶手缉拿?The mutilated corpse of an elderly man is dragged from the Thames. From his hand-made shoes he is identified as Lenny Cobb,an old lag who once testified against the notorious but long dead Kray twins who ruled London's gangland in the 1960s. East End historian Buchan believes it is the first in a series of copycat murders in the style of the Krays and is proved right when another ex-villain who gave evidence against the Krays,Slasher Gainford,is also killed. There is also a resurgence in violent attacks such as the mutilation of young Dan Street in a pub toilet,another hallmark of Kray warning shots. Prime suspect is surly pool hall owner Steven Dukes though Buchan thinks he is not the right sort. Strangely enough his more civilized business associate Jack Cheshire has requested that local officers Chandler and Miles stay on the case,rather than it be given to the organized crime squad.
