In the middle of the night, Nicki is once again haunted by intense feelings that she can't explain. A visit to the doctor is supposed to help and behold: the more he pokes around in the past, the more a connection between Nicki and her twin sister Karen becomes apparent. In addition, the two ladies are each pursued by a menacing man who roams the streets late at night with a knife and seems to be in cahoots with an oddball antiques dealer.
Das Kriminalmuseum was a German television series. It ran from 1963 to 1970 on ZDF and was one of its first programs. Each episode began with a tracking shot through an unspecified crime museum, stopping at one of the displays, whose story was then told. Each episode was between 60 and 75 minutes long and featured different actors as the criminal commissioner. The best known was Erik Ode, who in 1969 moved to Der Kommissar, appearing in 97 episodes. The theme music of the series was written by German composer Martin Böttcher, who also composed the complete scores for five episodes.
