"Naalen" is the title character in the film, a ruthless black market kingpin whose wake inevitably follows a series of other crimes. How "Naalen" got his strange nickname will not be revealed here, but it can be hinted that it has a close connection to the precious and rare commodity he deals in his "business": insulin.
