Detective Katrine Ries Jensen and legal psychiatrist Thomas Schaeffer form a special unit at the Copenhagen Police investigating serial killings. A case from Schaeffer’s past crops up. As a young psychologist, he held back from sending a patient, who was manically drawing the details of a traffic accident, to a secure hospital. Now these bloody scenes resurface, enacted as real killings.

Based on an original idea by best-selling Danish novelist Elsebeth Egholm, the series follows the inquiries of a special unit at Copenhagen's police force, consisting of detective inspector Katrina Ries Jensen and forensic psychiatrist Thomas Schaeffer. The pair specialise in serial killers that do not fit within traditional behavioural patterns.

Mads moves into a house with his lovely girlfriend Marie when a sudden pang of doubt strikes him. Is this the meaning of life? Has he lived out all his dreams? He drops everything, moves away from his girlfriend and throws himself into a desperate quest to live out his greatest dreams; a quest to find the meaning of life and the one and only.
