Part One starts at the beginning with tweets from Kim's friends, colleagues, and members of the public about a young woman who had strangely disappeared. After initially claiming that he had dropped Wall off, Madsen changed his story ten days later and admitted to "burying" her at sea after an accident. When the case turns into a murder investigation, a nation is horrified and transfixed. Part One delves into how a young journalist's life could be cut short in such a brutal manner.
Part Two delves into the judicial process in Denmark, while also painting a portrait of an unrepentant killer. Attempting to probe the mindset of Madsen, Part Two explores the nature of narcissism and psychopathy in the process. Madsen was viewed as a minor celebrity in Denmark, but his brash persona ultimately hid misogynistic and sociopathic tendencies. He was used to orchestrating his own story and public persona, but found that his powers of persuasion and influence had run out when he tried to evade culpability for Wall's murder. Those who knew him wondered what they had missed and whether Wall was his first victim.
