Season 1

THOSE WHO KILL is a crime series about a violent criminal who is surrounded by fear and mystique – the serial killer. Up until now, we have been able to curtail their activities with early - and effective - interventions via the safety net of a comprehensive social welfare system in Scandinavia. But times have changed. Borders have opened up, social welfare is in decline, and slowly but surely the whole system has become imbued with a sense of resigned impotence and callous disregard for those it once sought to rescue. The rifts in the net have become so large that bigger fish are slipping through the mesh, and as a result, a new type of crime is starting to burgeon - killings not grounded in traditional motives and patterns of behaviour. You need a very particular kind of person to catch the serial killer; Someone who knows and understands the killer’s dark side, and the fantasies that plague him - someone like our two lead characters, Deputy Chief Inspector (DCI) Katrine Ries Jensen and forensic psychiatrist Thomas Schaeffer - a police detective and a “profiler”, who in very different ways each possess a deep psychological understanding that connects them to the killer’s victims and to the killer himself, driving them to pursue each case to the end of the line, again and again.
