Series 2 premieres in North America May 16. Detective Peter Wendel wants to create an elite team of investigators to crack cold cases. When the police receive a tip that Sweden's most notorious serial killer is a fraud, and therefore eight killers might have gone free, Wendel gets his chance--but only the dregs of the force are available to work the case. Can his lowly group solve these high-profile crimes? Swedish with English subtitles.
