简介：　　Inspired by a true crime case, the fictional six-part series "German Crime Story: Gefesselt" follows the story of one of Germany’s most notorious serial killers, the so-called "acid barrel killer." Raik Doormann strikes fear into the Hamburg area in the early 80s and 90s, as he kidnaps, tortures and brutally kills women in his own nuclear bunker. It is not until Nela Langenbeck, a victim counselor and later homicide detective, comes across clues to his deeds. But at that time, women within the police department are regarded more as secretaries than investigators - so she initially earned headshakes for her approaches. Against all odds, she eventually gets on the trail of Doormann and his gruesome deeds.
